Pretty cool!

Some nice examples:

A collaborative pixel-based image builder: https://peace-robin-a2dw95.manyminiapps.com/

Analog synthesizer controlled by accelerometer: https://magic-gold-z13d9k.manyminiapps.com/

This is really cool! I am having trouble getting my iPhone to make sounds, so I couldn't quite test the accelerometer. But on the laptop just the default sounds is really pleasing.
