Vibed this theremin app over the weekend. I've been in a mood building music related stuff.

It's quite fun to play with, very impressed with how well the hand-tracking works. I've been busting my phone out while killing time and just waving my hands around making cool sounds. It's like magic, sort of.

All the code is on GitHub (it's just a giant HTML file)
