In between mooching around the space stuff, I spotted this, between a V2 rocket, and a cray super computer.

Still not sure how it works, but man is it pretty...

This thing is going to be huge!

 

It's pretty cool innit. I've been thinking of donating to the Long Now foundation... I really like the thought of that clock ticking along for the next 10,000 years

 

That is super cool. That thing alone would make a trip to the US worthwile. The hike, cave, doors and massive gears are reminiscent of something out of Myst or Riven.

 

An alternative "long" clock.

(probably NSFW in countries that care about that sort of thing)
