After searching for what seemed like forever, I was able to find a tutorial that told me how to make Anaglyphs out of a single picture, instead of taking two pictures and making them into one.
These ones do actually work!
I drew the second, and the first one I took myself about four years ago.
The first one totally trips me out. I can never tell if Anaglyphs work, but that one definitely does.
So seriously, go get a pair of 3D glasses and look at them. C:
