Hello Alextheyellowthing, If by 'Tag' you mean the graffiti, I used enamel paint and one of my fine brushes. Mmmm, not the finest mine you- I reserve the Kolinski's for much better things!
Alternatively, if you mean the stereo picture, they are easy, you just need a left eye view and a right eye view which you get by simply moving the camera incrementally from the left to the right. Its good to practice standing up, you put your weight on the left leg, then the right for the next shot. Taking care to keep a centre point and not moving in too much of a curve.
I then reduced the size of both pictures and put them side by side on a new file with paintshop. Some of your own outdoor shot would work very well in stereo or anaglyph.
