Hi,  
I’m trying to achieve a effect. I want to have some line organised like a tree.  
One end of the lines is fixed, all grouped together the other side is moving all the time at different speed. just like if i had some seed weed skeletom.

Not sure how to start: drawing API or basic drawing?  
how can i have a perpetual movement but with one node fixed.

not sure if i explained well , let me know

lets take [www.yuco.com](http://www.yuco.com) to illustrate, execpt that i want the line to move.

cheers
