what did you use to make this?

I use my digital camera. Alas it doesn't have one of those eye hole thingies, si I have to use something on the camera as a guide. I take one pic with my left eye and then slide the camera to my right eye trying to make sure it is level.

Then I transfer them to my computer I open the right eyed pic with Paint, extend the width to double what it is and then open the left eyed, copy it then paste it to the right side of the right eyed pic. Make sure it is a perfect fit then save. Open with a program to allow it to use most of your screen and then try to cross your eyes (Basically similar to those Magic eye thingies)

There ya go. Check my older stuff as I have a LOT more of these. XD
