With this small image manipulation tool written entirely in Tcl/Tk You will be able to create 3D pictures from Your own photos.
All You need to do is to take two photos from the same set with about half a meter (2 ft) horizontal distance, load them into this software, calibrate their positions and brightness, and export the result.
The resulting 3D picture can be viewed with any kind of anaglyph goggles (a small paper goggle with red foil in one eye and cyan in the other, or similar color combination). Anaglyph goggles are easy to get and cost about $0.5 ... $1.0 - the easiest way to make Your screen or pictures 3D.
