The Physics behind Snowflake creation, and other small things - The main problem that we cracked is actually getting an algorithm that is feasible at current levels of computer performance. We divided the problem into chunks 1 micron [millionth of a meter] on a side. Snowflakes actually form one molecule at a time, but the law of averages kicks in, so we can get away with this simplification. As it is, our model takes 6 to 24 hours on a standard office computer to make one snowflake -- which we call a "snowfake."
Animal Minds - A little cute, but a few interesting things.
