A nifty graphic with rotating & wiggling letters, bouncing balls, and rotating square packets.

Benchmark by using the menu to toggle the FPS display (frames per second), and touch the screen to display a slider, which increases/decreases the speed (move it all the way to the left to check your max performance).

Use 1 finger to move the text, 2 fingers to zoom, and 3 fingers to rotate. Double-tap to reset the position.
