This is a stereoscopic image ([link]
). To view it you need to stare in the center of the image and slightly cross your eyes until the two separate images meet to form one image in the center.
It is kind of hard to do but once you do it, it's really easy to do it again.
To my knowledge this hasn't been done with abstract art before, only photography. (please let me know if I am wrong)
I hope to do some more of these in the future!
Happy viewing, don't stare too long or you might get a headache!
ps. it's best to back away from your monitor a bit depending on what resolution you are running, if it takes up your entire monitor then it might be really hard for you to merge the two sides.
