I'm told I have above average soldering skills, but the beauty of the (very large number of) joints in the OP work of art floors me.
I actually had the idea of building an LED clock (using standard LEDs as pixels, rather than 7-segment display) a while back without using IC's.
This has pretty much destroyed my idea. Is that really the minimum necessary? Holy cow.
