The Camera lets you gather information (specifically, distance from nearest block) in your surroundings.
Recipe
NOTE: The stone bricks on top can be any type of stone bricks.
API
Redstone
Since 0.1.4, you can hook up a redstone wire to the camera to get distance data - the energy level reflects the distance (15 - 0-1 blocks away, 14 - 2-3 blocks away, …., 1 - 30-31 blocks away).
OpenComputers/ComputerCraft
