Requirements: Between .5cm and 1cm large. It must negotiate 3-D space in an air atmosphere. It must be capable of autonomous existence. It must be capable of high-g acceleration to rapidly start and stop. It must be able to remain stationary on a surface at any spacial orientation. It must self-replicate. It must derive power from organics such as sugar and poop. It must be able to detect and evade moving objects. It must exhibit a preference to orbit the heads of humans. It is desirable that it emit a general buzzing sound. The louder the better. Use: There may be broader applications for this device, but the primary use is as a response to the following scenario: If you are invited to visit the Large Hadron Collider, and some scientist there starts bragging about the colossal scientific instruments they have, a devastating response would be to open up a matchbox and say, "Oh yeah? Got one of these?", and let the machine leave the matchbox and hopefully begin buzzing orbits around the bragging scientist's head. Budget is tight.
