MOnSter 6502 - A Giant 6502 CPU

Now here's a seriously cool project - a giant replica of the MOS 6502 CPU that visualizes it's data flows with a lot of LEDs!

Incredible as it may seem, it is a fully working NMOS 6502 implementation (minus a few bugs that the developers aim to iron out in the next revision of the board), albeit running at just about 400 KHz due to the capacitance of the transistors used.
