Cecilia's Drawing Toy: Updated for Little Hands

You learn a lot about proper software design by actually watching users. This is a well-known fact, but sometimes a reminder is helpful.

Cecilia was in town for several weeks, so I got a chance to watch her playing with her drawing toy. I noticed that she preferred to hold the phone tightly with one thumb, which really threw off the motion tracking.

A few changes later, I added support for multiple-touch operations. If little hands need to grab the screen in two places, that's not a problem!

It's also good for finger-painting. :)

As always, the updated version is available on the Play Store if you're not in the mood to mess around with compiling your own.
