I guess I have too much useless information in my head.
Also, for an extra level of math-geekiness, here is a Sierpinski Valentine from one of my favorite web comic sites, xkcd:
I think it is a very funny play on the Sierpinski triangle, a famous fractal (a shape that exhibits self similarity, like clouds, beaches, rivers, leaves, etc.)
Anyway, if you fancy a girl or a boy who is into math, this info might come in handy next Valentine day, or not.
P.S. My 3-year-old daughter Tatia took the picture below using my wife's DSLR during the school trip. Either she is a very talented child or this confirms my belief that if you generate a lot of pictures, some are bound to be good!
