Intel is trying to generate a little viral buzz with a new video it’s promoting called “What’s a transistor?” It’s animated, and stars a frog.

What is a transistor and how do the hundreds of millions of them work on a processor not much larger than a postage stamp? Meet Haf the little frog who learns about a big change in technology. Transistors are the essential building block inside all modern electronics devices. Yet they keep shrinking, this time thanks to Intel’s hafnium-based high-k and metal gate technology. At 45nm, these transistors are so tiny that you could fit more than 300 million of them onto the head of a pin and more than 400 million of them will power Intel’s soon-to-be-released chips.
