my fav one has to be the SEXY one because it looks like Hinata
from Naruto (I am a mediocre Hinata fanboy)
It's very simple really. If you look at it frame by frame, you'll see that I just copied random parts of the image and dragged them in one direction and on the last transition frame I added some random parts of the next portrait.
The glitch out effect on the preview looks pretty cool. How did you do that?
