Helicopter Cheesecake

Wow. Jeff at Gravity Lens found a really cool helicopter: the CarterCopter.

So far, it's just a prototype technology demonstrator, but it has already achieved a milestone for rotary-wing craft: a mu of 1 for the first time in history (achieved on June 17, 2005).

Yeah, I didn't have the faintest clue what that meant, either, but read more about it here and keep your eyes peeled for these very attractive rotorcraft.
