Hmmmm 4 movies.... Depends whether they were as interesting as the X-men.

I'm going to have to check the details on the prizes to determine whether
these are "splitable". The robot arm I am much less optimistic about,
but the adder I'd want to do some calculations on the atomic diagram Mitre
has for a 1-bit adder to see if 8 of them will fit in the cube.
(The wording on this may get sticky -- what if it occupies 100 nm^2
but is only 10 nm thick?) If that is allowed, then the question becomes
can they synthesize them and lay them out so they function. If it really
has to occupy a 50nm cube, then it probably is much more difficult.
