Inspired by the "Explain your Username" thread, I wanted to ask people to explain their avatar's. Some people's avatars make sense, but others', not as much. I still can't figure out what the hell ETBJ is supposed to be.
Anyways, my avatar is a NAND gate. A NAND gate is an electronic circuit that takes two boolean (binary) inputs. It outputs "true" so long as at least one input is "false". The NAND gate is an important gate because most computers build all of their circuits around it. My avatar is the fundamental component of logic in computers. (The medal is because I won the popular vote on the competition to determine the site's slogan).
