3D can be done with two images shot at the same time (or in close succession) with the camera moved laterally to slightly change the perspective. To view with colored glasses, turn one image red/black and the other blue/black and overlay. Put on the glasses and you should have something 3Dish. I am sure there are other ways to do this as well.
 
Its called anaglyph, theres a lot of anaglyph software out there to use. Making them by hand probably wouldnt work well.
