A geek in a sea of nerds

You know I would like to think that I can geek it up with the best of them. I dig PCs. I love astronomy. Hell, I can name all five series of Star Trek (TOS, TNG, DS9, Voyager and - yuck - Enterprise. Did I say that out loud ...). But there are some recesses into which I will not clamber.

Behold, the binary clock. Time represented in binary. I could try explaining it to you but, honestly, to you give a hoot?

If anybody can tell me of a geekier gadget, I will go he.
