You can now record #GIFS! Try the record button. Note that processing takes some time, so I recommend trying a very short gif to begin with. Suggestions and feedback welcome. Thanks to u/BalintCsala for the implementation of gif recording!

u/lionleaf

(Note that gif processing happens in worker threads, so you should be able to switch tabs while waiting)

I should probably stop remixing this one, but I keep finding dumb small changes that make it look better.

Hey! Just a heads up; I removed your speech synthesis dweet, as it was on an infinite loop and autoplaying. If you can post in a way where it doesn't autoplay feel free to repost it. For reference this was the code: t||(s=speechSynthesis,o=new SpeechSynthesisUtterance("god"),o.pitch=9) c.width=2 a=t%.7*10 a>.01||s.speaking||s.speak(o) x.fillRect(0,2,a,a) . (Yes, we could use a better moderation system than leaving comments on other dweets ^^). Cool dweet btw, keep it up!

Was wondering how the shape evolves as the constant in C(99*i++) changes.

u/AnnanFay

Change 2e3 to 99 for a more vigorous experience.

Awesome!
