This one is one of my oldest work that I had done with the old version of Pure Anaglyphe (the one with only 4 levels of depth). I didn't have any knowledge of GIMP and I had to cheat to have more than four levels of depth. But I'm considering to do some remakes of my works with the softwares I'm using now (if I have time for that). I think it could be interesting.
And thanks for the fave too !
