Megaphone creates interactive displays for public places, letting passersby call in with their cell phones and, in real time, control what happens on the screen. It’s an engaging and unique way to interact with a customer.

Below is a demo showing a display created for Sprint. Using just their voice, the callers create live modern art.

This interface, designed for a Palm Centro launch party, interfaces with up to 10 players using the number keys to control objects on a screen while they compete in real time.
