Original file by Yvette Hamilton (vimeo.com/user2834117) here on Vimeo.
I wanted to have a projector look on a "Project in an Hour" project I did yesterday and I didn't want to recreate the effect in After Effects. I found a clip by Yvette and looped it while still keeping the sound going the same.
So download away and see if you can use it for whatever.
The project I used it on can be found here (vimeo.com/15612233).
