Pause: A Relaxation App for iPhone

After opening the app, you simply place your finger on the screen and slowly and continuously move it around so that the airy orb of color floating beneath your finger gathers smaller orbs like itself, growing larger and larger until the screen is filled.

I've been playing with this app for a few weeks, and have found myself really liking it. It's a great way to create some space for your brain to catch up, and figure out what to tackle next. While it seems really simple, it also works really well.
