Per my eagerness to play with my new toy, I discovered a neat little program that is a nerd's dream come true. Spacetime 3.0 is a way cool and easy to use math program for the computer and iPhone.
Ok, I know, most of my readers won't care one diddly-squat about a program that most everyone can only use the tiniest fraction of, but I found it terribly fun! (Even though I can't use most of what it does.... yet.)
I found myself endlessly amused by all the little 3D movies of complex (and meaningless) trigonometric functions I made. It was so fun, in fact, I made a YouTube video of my results. Here ya go, enjoy:
