Off-topic, but cool:


A guy selling kits to make a all-parts-exposed digital wall clock that 
uses *no ICs* and *no crystals*.  You build it yourself, 1250 parts to 
solder onto a custom board.  Too pricey for me, otherwise I'd love to put 
one together.

ICYW, I dug around the FAQ and he is cheating a bit: he's using the 60Hz 
of the AC as a timer source.

Hmm, since it plus into AC, does that mean touching some parts of the 
exposed circuits might give you a nice zap?
