Researchers build an 8bit pneumatic processor!

Hey, who read Ted Chiang's Exhalations? Did the idea of the pneumatic brain (and for that matter the whole physiology of the stories beings) that the main character found out that every person contained, trip your trigger? Did it seem a bit improbable however? Well check out this article that I found on Make Magazine's site:

• Researchers Minsoung Rhee and Mark Burns at the University of Michigan have created an 8 bit processor using logic gates made of pneumatic valves.

What is even wilder is they have videos of logic states, (flip flops and what have you) working!
