There's a library on Linux for talking (via bluetooth) to the Nintendo Wiimote (aka. IR Camera). Two years ago I used this to make "Pong Hero" for the linux.conf.au Open Day.

But now a part-time single parent, my priorities have changed. Rather than designing games for kids from 5 years and up, I see opportunities to strap IR LEDs to babies and see what happens!

A heartwarming tale of technology and child services. 2 star.
