Although moving cockroach legs is fun, these guys have made a significant contribution to science. The "SpikerBox" they created allows individuals to record EMGs and see the recruitment of individual motor units, be it with a cockroach or a human. When I did this in college, it required thousands of dollars of equipment, none of it was computerized, and it only recorded to paper traces. For $100 people now have access to equipment you previously only saw at universities.
