Who remembers the 90’s demoscene?

After many, many years… I finally made a basic demo using JavaScript and [http://codeguppy.com](http://codeguppy.com) (a p5.js-based platform).

What you see is not a video – but an actual JavaScript demo.

▶ Run the program yourself (just press Play):

- If the sound doesn’t start … stop the program and run it again… it is a small bug. Or you can use this link to start it in a new window.

Feel free to remix and share your new version!

P.S. I may create a similar demoscene program in the future. If you want to contribute a nice animation or creative effect, please send me a message! Thanks!
