I have been trying to make my company logo with a little animation. here it is:

I want the swoosh on the top of the logo to have a mask to make it look as if someone was drawing it. and then having it repeat it over and over again. Can anyone give me some ideas on how to do this or help me out with it. your help is much appreciated.

Thank you,
