World's Strongest Chessman
Combine ``Rapid Chess'' with the ''World's Strongest Man''
competition. Let the board be populated with very heavy
life-sized pieces (perhaps made of stone) which the two
players have to move around to checkmate the opponent.
Imagine the strategy: By chasing the (say) very heavy queen
all over the board, one player can force the other to run
out of time on the clock.
The trick will be finding strongmen who play chess, though.

802.11{b,g} cell phone
How difficult would it be to make a mobile telephone that
communicates over Wifi (802.11b or its successors) and works
over AIM (iChat AV) or Netmeeting (that is, it doesn't have
a phone number). And deploy in a place like MIT that has
wireless everywhere free for students.

Clipped Circle
The area of a circle clipped by a square as its radius
increases from 1 to sqrt(2) is
0.25*A = h + (pi/4 - atan(h))*r^2, where h=sqrt(r^2-1)
(Dimensions sure are funny, aren't they.)
