Quite possibly the most useless psychological questionnaire ever devised.
Displays over six quintillion variations of the Dogs Playing Poker painting, that venerable jewel of American fine art.
Simple way to generate and visualize Markov text chains, which power the most annoying bots on Twitter and the rest of the web.
