The result was SchellingFlags.
SchellingFlags is the meme of “…but on the blockchain” applied to flags, with a touch of Art & Language and Komar & Melamid. You can find out more about it on the project page. The version shown is from during development, so the last two flags haven’t been voted for and thereby defined yet.
Massive thanks to Gray Area for putting on an awesome event and making my work part of it!
