Very cool! It's like shadertoy for canvas. The 3rd example I got in the slideshow was this one, which struck me immediately because of the greek letter variable names... awesome! https://www.dwitter.net/d/855

Worth visiting the "top" list: https://www.dwitter.net/top

Would be cool to be able to post sound loops in the same style. You could use this web audio module for that: https://www.npmjs.com/package/jsynth

I LOVE this idea....

I have been working on Glitch for a while. Not forcefully limited to short tweet-size tunes, it makes generative music from simple chiptunes [1] to something more advanced [2].

I would be happy to answer any questions, if you are interested in!

It's open source and new version is coming soon - https://github.com/naivesound/glitch

This is awesome!

Added a new feature: Trig function (sine, cosine, tangent) morphing by beat & FFT buckets. Looks trippy and goes well with glitch/ambient/IDM: https://dweetplayer.net/demo/v1/*/1829@10f,683f2,3313f1,915f...

Very cool. Might be a good idea to add a volume slider instead of just toggle, since that's often easier to get to than system volume.

Also, if you're interested in some background and process, here are the slides from the Toronto Hack && Tell presentation I gave last week: https://docs.google.com/presentation/d/19tQgPg9Wb9xwuregHCGF...

Always been so impressed by what people make on Dwitter only having 140chars of code. https://www.dwitter.net/

I remember having seen this a while ago and having been unable to find it since. Thanks for posting this, its always really cool to see what can be done in such a little amount of space.

Reminds me https://forthsalon.appspot.com/

Loads to about 90% and freezes. I'm on iOS 10.

Thanks for reporting that. I suspect it could be this known issue where I didn't anticipate autoplay for media to be disabled: https://github.com/atesgoral/dweet-player/issues/8

On Android it loads to 90%, freezes, then works normally after 10-15 sec. Although low fps.

The "freezing" is when the audio track is still taking time to load. The dweets themselves load in an instant. Yeah, FPS will unfortunately be an issue on slower devices :(

Safari/Mac same issue as iOS 10.

Chrome/Mac works great.
