For Pi Day (March 14), I taught a bunch of high-school kids about using Trigonometry for video games! I think there were some lights going on! (We also ate Costco pies). Watch these videos to learn for yerself!
I'm still amazed at how these kids can crank out the answers to equations, but don't know anything about practical applications of Trig...
When did Trig "gel" in your brain?

I recited pi to the thousandth digit from memory and solved a couple of Millennium Prize Problems just for fun, then hung out with Pythagoras and his buds for a while. We ate freshly-baked pies and got drunk on cheap box wine. Good times.
