Electric Sheep still works great to this day. The lifetime membership is worth it if you want nice enough sheep with 0 effort, but there are countless HD packs on archiveorg and elsewhere

cool to hear that the actual electric sheep project is still something you can interact with!

For those super new to it (like me), check out https://electricsheep.org/ og video we came across it with https://www.youtube.com/watch?v=O5RdMvgk8b0 (this was just the first I found when looking there are many on youtube) and the algorithm behind it https://flam3.com/ This is all AFAICT as someone who's only just skimmed the surface, but i find it amazing.
