During WWII the Army Air Corp commissioned watches for the navigators aboard bombers. These watches had a 24 hour dial and were adjusted to run 4 mins. fast per day. They used siderial time rather than solar time. This aided in celestial navigation. I'm sure this was a fairly common practice in naval navigation as well; but I only have person knowledge of this example.
"In our three dimensional world we can visualize an example. If we were to take a three-dimensional cube and collapse it into a two-dimensional edge, and then again reduce it into a one-dimensional point..."
Last I checked, an edge is one dimensional, and a point is zero dimensional. 1337 math skilz dude!

... can anyone say Hokey-Pokey?
Depending on the target age; give them some appropriate programing tools like MSWLogo or UCB Logo. Let's make hackers of them all!

Inverse square law, perhaps.
