Bubble Logic

MIT researchers Manu Prakash and Neil Gershenfeld have succeed in creating a unique form of binary logic using tiny bubbles to simulate a computer's computational ability, allowing the potential for these bubbles to carry a tiny chemical payload that may have implications for drug-delivery systems built from tiny microfluidic circuits. You can see an example of their work here or read their paper in the journal Science.

Very cool.
