HYPERBLAM by Heydon Pickering

“HYPERBLAM [created by Heydon Pickering] lets you make music with HTML. It’s a declarative implementation of the Web Audio API and is completely dependency free.”

I haven’t read the site that much yet, but their documentation & guides look well written and visually nicely designed. Especially like the hand-drawn illustrations, as it makes the site look a lot more human-made.
