[dbarbarian]

A collection of polar movements.

Move the mouse around.
Most look the best when you move the mouse from point A to B and don't shake it around.

EDIT: Forgot to thank Sinister Shadow for the property assignment idea. :)

neat!

[dbarbarian]

Thanks :)

[squan]

Damn, that's some wicked geometry/math ... whatever it is with the numbers :).

Lovely particle-thingy.

[dbarbarian]

Yea, never imagined that math would come in handy before I started working with flash. Glad you liked it. =)

[kdd]

that's cool. :thumb:

[icio]

That's really cool :thumb:

[hybrid101]

really smooth on my computer, dbarbarian, i love all of your works!!!

[dbarbarian]

Thanks :beam:

hybrid101: That's good to hear. I was a little worried about speed issues, with up at 50 particles calculating a bunch of stuff each frame.
I hope I don't dissapoint with future entries :)

OMFG that pwns, gotta be the best one i seen so far.

The points redraw themselves everytime the mouse is moved instead of just moving to the mouse point right?

I see a discrepency everytime the mouse is moved.
