This thread is for extreme geekiness/nerditude. What about you makes you a ginormous geek? If you were one of the "cool" people in school, this thread is not for you (unless you were only "cool" within your own little geek circle, of course).
Back in 2000, I was a sophomore in college taking a course in digital logic design. AND gates and OR gates and all the stuff you can make from them. We made a few basic circuits, the first lit up a 7-segment display (it's what the numbers on your microwave or digital watch look like), another performed basic operations with a 4-bit register and extremely basic 4-bit ALU. In my roommates' senior year, they both took the sequel to this course, where they had to make an 8-bit multiplier circuit. I took the same course a few years later, but they had completely changed the course material (for the better, since I got to do Cell programming). Well, I've been bored recently and in need of brain stimulation, so I went ahead and made the multiplier.

Y'know, for shits n' giggles.
