That is really creepy.
I gotta tell you I got a little creeped out when I was making it.
In Photoshop, I took the current image of Obama, rotated it slightly, removed the color, added noise and cut him out of the background he was in.
When I resized his face to match Guevara by making the layer semitransparent so I could see both of their eyes... it was very weird how closely they matched up.
