Instant Headache Tutorial

Stereoscopic images are difficult to make and difficult to watch. You need special glasses and screens or projectors. But here in the Forum is a tutorial by Bert to produce autostereoscopic images with GIMP!
Headache pills not included, but I’ll try to land an advertisement deal with one of the Pharma Giants. 😉

EDIT: The image is now less disturbing and the tutorial updated.
