My latest interactive projects is "Help the Earth" an educational eco friendly game for Google Play.
In this video you can see how it developed over the week or so I spent on it:

"Art that looks back"

My last published app "Following Eyes" is based on face detection and is on the googleplay store now. 
I have plans to use this technology for interactive art displays and games for the craic.

I've also been experimenting with Android TV using webcams to detect viewers motion.
