Real Life - 4 dimensional non linear graph (i-j-k-t) This was taken with a camera and not created in Illustrator.

This photo is the basis of my multi-parallel/multi-dimensional universe theory.... There are people walking away from the bottom of the stairs on the left hand side.... We cannot see them and this was a over a minute long exposure.... Where did they go ? It demonstrates how another universe could be in our midst without us even being aware of it... Photo is untouched ....and the experiment has been repeated many times...
