We mentioned PolyFauna last week, and now I've had a chance to look and listen. This free app from the rock band Radiohead is a trippy portal to another dimension. You start up with a dark screen that gradually lightens and you see a sort of alien environment. Is that snow falling, or stars? Am I under water? What are those strange skeletal creatures floating by?
You navigate by moving your screen in any direction. Every so often, a red orb appears. Intersect it, and you'll be transported elsewhere. You can draw on the screen and create some of your own "life forms."
