Sometimes when all you have is an industrial laser cutter, everything looks like an opportunity to create a real-life version of Space Invaders.

Martin Raynsford, co-founder of laser-cutter purveyor Just Add Sharks, combined one of the company's Whitetooth A1 cutters--which features an 80-watt laser tube--with an array of advancing paper space aliens, in order to mimic the 1978 arcade classic. In the original game, you control a horizontally sliding laser cannon and attempt to shoot down hordes of invading extraterrestrials, who slowly advance upon you and try to shoot you in return. With Raynsford's real-life version, a player simply controls the laser cutter via laptop keys, and a webcam allows them watch as their "space gun" burns the invading paper menace as they march closer and closer, thanks to a moving platform built on a modified rotary attachment.
