Over the past few decades, the Space Invaders have been tamed. Formerly vicious killers, the systematically brutal alien race now lets of steam by waging war on water rings.
Comprised of 200 tiny walnut and maple squares, these Space Invaders coasters run $US50 or five. At that price, you might not want to assemble a whole army as tradition dictates, even if it means you need to scale back that demented drinking game you just thought up. [Etsy via Geeky Gadgets]
