NAME
wiggle.pl - wiggle stereoscopy
SYNOPSIS
perl wiggle.pl left.jpg right.jpg out.gif
DESCRIPTION
Produces an animated GIF that displays left, then a blend of four images leading to right then back again. The left and right images are displayed a little longer.
If the left and right images form a stereo pair (and the order doesn't really matter) the output animated GIF is useful for wiggle stereoscopy.
CREDITS
Dan Oppenheim <droppenheim@yahoo.com> described the effect and asked how to implement it.
