Hey guys,

I have a question probably more about individual preference, but I just can’t replicate this effect. At this website there are several curvy lines that grow and draw on screen:

I don’t know how to achieve this by masking out the line, because the lines are curved. Is there anyway to animate the shape of a mask, and not just the position/scale??? That’s the only way I can think that they get them to draw so smoothly.

Any ideas?
