Wow, these are great! The back tap feature seems really handy, and it even worked with my case on. I guess they're doing it by sensing phone movement/rotation rather than some sort of touch sensor on the back.

The accelerometer (the one that knows your phone is rotated) is watching in three dimensions.

A tap on the back looks like a very brief acceleration on the axis coming out of the screen. Like a reverse free-fall.
