nice, well done

Amazing ! A true optical illusion ! Is hypnotic.My head is turning.
Did you try it with something else than cogs ? The color is important ? I'm not a good photosopper but i will try to reproduce it with another photo, roots or something like that.

thanks a lot both of you..and billyboy I have discovered that anything with radial blur(zoom) is brain scaring and cogs are additional illusion...you can try with anything,,..but the pointy teeth of cogs..got fully set with the zoom blur and created a better brain scaring photo..

Fun idea. I wish you had followed the horizontal flip with a vertical flip, however, so the final result wouldn't have quite such a mirrored-halves feel. (BTW there's a white-line edge issue where the top two cogs intersect.)

nice entry........... all the best to u ................

Look at the center of the image, then you move your body forward and backward... it's really crazy!
Very well done, author!

thanks for your comments...and erica I was experimenting with it and I turned off all the room lights and watched it full screen ......I have seen cogs everywhere after 5 minutes ..and the dizziness oh god ... .am not gonna try it again.

nice work.....
