Here's a neat site on snow flakes:
It by Kenneth Libbrecht and his work can be found at snowflakes.com

just thought I'd add this image to see if it works

And it does

Looking at the enlarged snowflake reminds me of the Nova show on PBS last week. It was about 'Fractals' and their style of geometric mathematical formula tends to reproduce itself in nature, forests, etc.
The show was called 'Hidden Dimensions of Fractals' or something like that. It was a neat interesting show.

P.S. It odd to realize that my 25 year old pickup truck with a snowplow on it pushes piles of those delicate frail looking flakes around.

Here's a great rendition of a 3D Mandelbrot fractal, aka Mandelbulb

And some more info on Mandelbulbs plus the're loads of links from there.

Cool !

P.S. In the next week or two I'll try to repair a little hole in the bottom of my polyethylene kayak by melting some of the plastic from the top of the kayak onto the bottom hole of the kayak.
In order to prepare the bottom hole area to accept a bond, I'll need to gently heat the hole area to the point that water will not bead on it.

That was mesmerizing! I guess I never considered how a water droplet would stay in droplet form rather than breaking apart, as if it was contained within a shell. It took speed to shatter it!
And, as the two drops combined they continued to have more volatile movement. Cool... :)

Thats was an interesting 'round' video, cute to watch.
I wonder if anyone has a mind that can figure those things out before they're demonstrated. It seems like playing chess and knowing every future possible move.
Speaking of shapes and fractals, it is starting to snow a little bit here, another incredible view, Gil.

One of the best explanations of relativity I have come across:
