Pink Trombone
A little while back I used this combined with a physics simulator to make a toy where you throw polygons in the air and they scream: https://ohgodwhathaveidone.stackblitz.io/Code's here if anyone wants to play: https://stackblitz.com/edit/ohgodwhathaveidone – I did a fairly medium job of abstracting the synthesis engine away from the UI, but it might be a decent starting point if you're looking to make other Trombone-based web silliness.
