LaserBox is an interesting little puzzle game about guiding lasers through boxes in an attempt to uncover the hidden mirrors.

Lasers and 'Impulses' can be fired from one of four directions into the group of boxes and will proceed to bounce around and eventually come out somewhere else. Depending on where it pops out, you then need to work out where exactly it could have bounced and implement a Minesweeper-like removing/tagging strategy.

The number of boxes can also be increased to give more of a challenge for anyone finding it a little too easy. Give LaserBox a go at Newgrounds.
