Dwitter

Dwitter is a community of coders posting tiny visual demos, each constrained to 140 characters of JavaScript. When you arrive, you see a feed of looping animations, and you can browse by hot, new or random. Each one shows its code, so you can read the whole thing in a glance and marvel at how much happens in so little. The results are astonishing: swirling tunnels, bouncing shapes and 3D effects from a line that would fit in a tweet. It is a rewarding place for programmers who want to learn tricks, and a hypnotic one for everyone else. Because it is community-made, quality varies, but the random list is a fun way to browse. Open a few demos, look at the code, then try changing something. If you like this, tixy.land and Shadertoy are similar corners of the web on our list.
