But they are snowflakes, and they do often look very much like that. 
Language issues?

BTW, a gentle snowfall can be dangerous, things can get very slippery 
and visibility can be very low.

Perhaps. According to my Oxford dictionary, snowflakes is the 
collections of snow crystals, in which snow falls, i.e. several crystals 
bunched together.

I was thinking more af being hit by large icy ninja stars :)

Well, when the snow is damp, the "flakes" do bunch together. The flakes 
aren't a random assortment of individual crystals, though, each flake is 
a crystal. A snowflake is a snow crystal in every definition I've seen 
until now.

Here's a good site I just found, lots of interesting stuff:
http://www.its.caltech.edu/~atomic/snowcrystals/
Hmm...one of the people who did stuff for that site was a Patricia 
Rasmussen. A relative? Anyway, they seem to use your definition...I 
don't know why they call a flake a crystal and a clump of flakes a flake.

Well, they are only a couple millimeters across, so that isn't much of a 
problem. They do hurt when it's windy and cold, though.

You don't get snow where you are?

Not that I know of. (Rasmussen is a very common name in Scandinavia.)

Could it be that I am right :)


> You don't get snow where you are?


It has been known to happen, here in Denmark. It just don't seem to fall 
as individual crystals, always at larger agglomarates i.e. flakes.


I think we'll just have to agree that we disagree, and stop this, before 
we are sent to off-topic.

Or that it is a regional thing...as I mentioned, I'd never heard that 
definition before.
The main thing I don't understand is: why are clumps called flakes? They 
aren't flake shaped, the crystals are (usually). The clumps are just 
irregular ball shapes, sometimes (relatively) big chains. Maybe I'm just 
expecting things to make too much sense.

Thats an old topic, and I know that now are better snowflakes models.

But while I'm reading this I have one idea.

I belive its L-system with 60 degree rotation six elements and decreasing
length. Am I right?

What about random elements? What about make it a 60+((rand(ANY_SEED)-0.5)*
SCALE, (where SCALE is quite small) rotation and length decreasing with
also random scaling? And maybe a random #if ? For example :

#if rand(seed)<0.96

// make next recursion step

#end

When i have more free time I'll try to make that snowflakes.

Woland.
