There are a few dozen ASCII arts in the blockchain.
Almost all of them are copy pastes of stuff present elsewhere, or boring high resolution ones auto-generated from images. But hey, it's still fun to see.

Both men look quite similar, so quite likely it's the Winklevoss twins, who had a big and later catastrophic involvement with Bitcoin. The tip address appears to be cropped and is incorrect, ooops. 777db7bfbea2c525d5adb05a8fbf47736e2311492f4614e5d38ab199b4bbfac2 give the likely correct version of it "1MDBHLgv7WX9viRG9X4LfDQfCX8oZ9wviC".

    Code 1. The Hashling.
    "The Hashling" presumably refers to a cute fictional crab-like animal that somehow inhabits the alternate reality created Blockchain network's incredible hashrate. Yet another souless NFT collection would later be created with that name as well: magiceden.io/ordinals/marketplace/hashlings.B
    But that is not all! Immediately after the ASCII art encoded as one constant, the remaining constants of the input script except for the last one encode a raw PNG image with a hand drawing of the creature:
    https://raw.githubusercontent.com/cirosantilli/media/master/bitcoin-inscription-indexer/data/bin/a96bda1363e8968f45b05e3c1940ba37b18de53de0157d453ca9bfc44913768c.png
    The last constant is then the only thing that matters and spends the incoming output.
    The ASCII art and image are also inscribed 16 more times on the blockchain: github.com/cirosantilli/bitcoin-inscription-indexer/blob/master/data/hashling. 453c9511ca76361c8c44b4302ce1b5d8d5c98a938b548478ef931baaa7d70e62 also has the image without any ASCII strings.
    Peter Todd is the author of Peter Todd's hash collision puzzles. @BraveTheWorld is presumably twitter.com/BraveTheWorld, but it is less clear what are they.

    and starts a long chain of contiguous transactions that renders Santi's face twice in low resolution. They are encoded one line every two transactions with OP_RETURN:
    and we've decoded it manually in Vim.
    Both blocks were mined by AntPool, so they weren't mining themselves to enforce ordering. So how is ordering assured? TODO are transactions actually contiguous in the block or are there other transactions interspersed? According to:

    To my dear friend Mariano, por muchos anos más de diversión!
    the Spanish part translates to:
    Here's to many more years of fun
    It does not show well in our ASCII jumps because the non ASCII characters are UTF-8-encoded. Europeans... This is followed by the ASCII art with Marian's nerdy face in it:

    The message is encoded with OP_RETURN payloads across multiple transactions, 40 bytes per transaction. They actually managed to upload two almost fully consecutive transaction blocks and in the correct order. Could they be miners?
    Some of the payloads contain newlines, you are just supposed to paste all payloads together to form the image. Our reconstruction here is manual however, lazy to script it properly.

    vaardig regulerend de orde van de dag
    Is in Dutch of course, literally:
    skillfully regulating the order of the day
    Given the date and language, it appears to be a reference to Koningsdag, Dutch national holiday that celebrated the birthday of their King at the time, King Willem-Alexander. Born in 1956, he would have been turning 60 at the time, so a nice round number in 2016 when these birthday candles were inscribed.

    Code 4. Study Math and Computer Science at Augustana College.
    Contains ASCII art of a large letter A. Has some custom encoding we didn't have the time to investigate which makes it deformed in our dumps, so we fixed it manually. The associated message reads:
    !Study Math and Computer Science at Augustana College!
    and so we understand that the ASCII art is formatted to look like the font of the logo of that university from Illinois.
    Figure 10. "Augie A". Source. Off-chain reference image for the inscribed Code 4. "Study Math and Computer Science at Augustana College" typeface logo taken from the Augustana College website.
    Data Insertion in Bitcoin's Blockchain by Andrew Sward, Vecna OP_0 and Forrest Stonedahl is a paper published by some people of the university, presumably the culprits. This was brought to our attention via: twitter.com/ottosch_/status/1735297943563837726.

It is encoded one line per transaction with OP_RETURN, but the ordering is completely scrambled. A link is given: TDAmeritrade.com/Blockchain but it is 404 as of January 2024 of course, companies can't keep their pages up for more than 3 seconds, but there is an archive which decodes the indented picture for us, including the corresponding tx hashes for each line web.archive.org/web/20180902001329/https://www.tdameritrade.com/landing-pages/offer/blockchain/index.html?cid=TVTDACDDRTVJ64, here is a copy from the website because we were lazy to double check each line:

    At firs we thought it was some kind of tribute to the Cannes Film Festival, but given the string "Titanium" and the fact that all people mentioned on another section of the art work for advertisement companies, we understand that it is instead almost certainly about the "Cannes Lions International Festival of Creativity", previously "International Advertising Festival", which has a "titanium" prize category, e.g. as mentioned at: www.thedrum.com/news/2018/06/22/cannes-lions-winners-titanium-glass-grand-prix-good-and-more:
    The highly coveted Titanium Lions - created to honor marketing work that doesn't fit neatly into traditional categories
    The part with the at signs '@' which we believe represents the lion is the hardest one and we've perhaps gotten some lines wrong, corrections are welcome.

    The actual code appears to be:
    OPRETURNISMYFRIEND
    a reference to OP_RETURN. It is steganographically encoded diagonally across the skull's eyes. Ciro Santilli only saw this after grepping: 
    grep @ data/out/0538.txt
    which made all non @ signs stand out due to the terminal's syntax highligh. This image was uploaded one line per transaction with a few interruptions that we removed manually, and there were was a previous partial attempt a bit before: at tx f8102999c0aaf7681deec383eb8e7946f093e94a116a21e367e9ed6b7c32d1fb so either a failure, or maybe it was intentional to obfuscate things a bit.

    @   ###########*    @   ###    ###'     @    ########       @   ###    ###*     @   #########*      @   ###     ###"    @    /#########     @    ########/      @

@   ##<             @   ##########      @   ###    ###]     @   ########(       @   ##(             @   ###########     @   ####### ###     @       ###,        @
@   ###\.           @   ###    ###.     @   ###\   ###      @   ###     ##.     @   ##\             @   ###     ###.    @   ###     ##/     @       ###         @

    and the rest is just more of the same, just 10x longer. Manually converted to horizontal form to not take up too much space here.

grep -n -r 'XXX' . | sort
grep -n -r '...' . | sort
Tribute to computer security researcher Len Sassaman, who killed himself on 2011-07-03, starting with an ASCII art portrait followed by text.
Because it comes so early in the blockchain, and because it is the first ASCII art on the blochain as far as we can see, and because is so well done, this is by far the most visible ASCII art of the Bitcoin blockchain.
Transaction: www.blockchain.com/btc/tx/930a2114cdaa86e1fac46d15c74e81c09eee1d4150ff9d48e76cb0697d8e1d72 from 2011-07-30, a few weeks after the suicide.
Created by famous computer security researcher Dan Kaminsky and Travis Goodspeed, presumably this other security researcher, evidence:
"Bernanke" is a reference to Ben Bernanke, who was one of the economists in power in the US Government during the financial crisis of 2007-2008, and much criticized by some, as shown for example in the documentary Inside Job (2010). As hinted in the Genesis block message, the United States Government bailed out many big banks that were going to go bankrupt with taxpayer money, even though it was precisly those banks that had started the crisis through their reckless investment, thus violating principles of the free market and business accountability. This was one of the motivations for the creation Bitcoin, which could reduce government power over economic policy.
It is worth mentioning that there do exist some slightly earlier "artistic" inscriptions in the form Punycode inscription in the Namecoin blockchain, but as far as we've seen, the are all trivial compared to BitLen in terms of artistic value/size.

Len was our friend.
A brilliant mind,
a kind soul, and
a devious schemer;
husband to Meredith
brother to Calvin,
son to Jim and
Dana Hartshorn,
coauthor and
cofounder and
Shmoo and so much
more.  We dedicate
this silly hack to
Len, who would have
found it absolutely
hilarious.

From the JSON transaction we understand the encoding format: 
   "out":[
      {
         "spent":false,
         "tx_index":0,
         "type":0,
         "addr":"1CqKQ2EqUscMkeYRFMmgepNGtfKynXzKW7",
         "value":1000000,
         "n":0,
         "script":"76a91481ccb4ee682bc1da3bda70176b7ccc616a6ba9da88ac"
      },
      {
         "spent":false,
         "tx_index":0,
         "type":0,
         "addr":"157sXa7duStAvq3dPLWe7J449sgh47eHzw",
         "value":1000000,
         "n":1,
         "script":"76a9142d2d2d424547494e20545249425554452d2d2d2088ac"
      },
...
      {
         "spent":false,
         "tx_index":0,
         "type":0,
         "addr":"157sXYpjvAyEJ6TdVFaVzmoETAQnHB6FGU",

      }
So it is really encoded one line at a time in the script of the transaction outputs.

The transaction before the ASCII art tx 9b08c00ced2bca4525d74e82db9af2aec8ef213eb1c1bf68a48b6be929968332 starts with what is likely a "Legalize" and must be a Tor Onion service:

ASCII art of a Force of Will, a famous and powerful Magic: The Gathering card first printed in 1996.
This is Ciro Santilli's personal favorite ASCII art he has found in the blockchain so far. Also Ciro could not find any other previous source of this, so there is some chance it is original. One can dream.
The choice of card is probably linked to the function of the card in the game of Magic: The Gathering. This card essentially prevents the opponent from casting a spell they are about to cast. The presumed intended meaning of this art is further accentuated by the old card type term "interrupt" (late renamed to "instant"), which suggests that "this ASCII art is an interruption to the normal monetary transactions of the blockchain".
One of also reminded of the prayer wars interruption attempts. We could not however identify anything specific that this ASCII art might have tried to interrupt besides the normal flow of monetary transactions.
If one goes full art critic mode, it is also tempting to draw a parallel between the card's "You may pay 1 life" alternative casting cost (as opposed to 5 mana, 3 and two blue, which is a very large cost for most games) as being a reference to the money spent by the uploader of the art to upload it.
TODO understand exactly how it was encoded and why it is so weird. The UUUU has a slightly weird encoding which we fixed by hand here TODO understand.

Erich,
Bro, this looks excellent!!
-Duriel
suggest this ASCII art might have been uploaded by Figure "Erich Erstu", AKA Hyena, creator of cryptograffiti.info, a service which would have allowed uploading ASCII content to the blockchain.
The only other mention of "Duriel" in the blockchain is tx 140562ceb42fc8943fa52ccc0ddbb11ca2d88dae9b5240d7a4b46864538c515a which has some freedom of speech comments and gives the email: 
Duriel@paystamper.com = 1HcuhfTAiQCt6KdMG2rZLXsTcKYj9nLDhS
paystamper.com was some other blockchain service from circa 2015:
The following almost certainly contain ASCII art but we were not yet able to decode them. Puzzle solvers from the Internet, we need your help!

The Bitcoin message is acknowledged on the website at:

    She apparently lived in Germany as the website is bilingual German/Chinese, the text:

    means:
    We miss you
    TODO decode properly. It is encoded as P2PKH keys (20 bytes at a timt) but also contains its own newlines and trailing spaces. Maybe a start:
