Making computers out of molds

Spore-Spitting Slime Molds Make Great Computer Hardware | Wired Enterprise | Wired.com: There has in recent years been an explosion of interest in using alternative materials in computing. Some are inorganic, like the use of the nanomaterial graphene to create atom-thin transistors. But the use of living systems is one of the most captivating areas of research. The University of Leeds is trying to use bacteria to build hard drives, and there’s even potential to use salmon testes in storage devices.

And... Rucker predicted it! :D
