Lumen

Warning: Time waster ahead.

Lumen is a simple and beautiful puzzle game for OS X and Windows. The objective is to light up checkpoints by bouncing, coloring, and maneuvering a laser beam through obstacles. Although puzzles may seem easy at first sight, the can be quite a challenge. The careful attention to detail and the colorful graphics make Lumen a joy to play.

(And what a great looking site too!)
