I’ve submitted my own entry which you can view here,
it hasn’t been updated to the latest version yet but I’m sure it will be soon.
Compared to some of the entries my demo looks a tad boring, but I really enjoyed putting it together. Condensing a script that was originally over 3.5k down to 1024 bytes was a real challenge. The last 20 bytes in particular were a pain in the backside! In version 0.2 I hit 1024 bytes exactly as I hadn’t realised you also have to style the demo page slightly if you use a black background. I think I may be able to shave a couple more bytes off, but I’m really coming close to the limit. The resulting code isn’t pretty and in no way readable, but it works! Take a look for yourself with a “view source” on the demo page.
