It's not an optical illusion, those really are small cows.

Assuming this is a sensible question (and who can tell here!) I'd suggest Bristol University Vision Institute:
http://www.bristol.ac.uk/vision-institute/
The world authority on illusions and visual perception, Professor Richard Gregory, worked there for many years.

Are you sure you can't instead use this illusion to somehow rob a bank?

Do you ever wonder why the reflection in a mirror reverses left to right (or vice versa) rather than from top to bottom?
Once you figure out why, its not hard to make the illusion do that.

I love that mirror paradox - it fascinated Lewis Carroll. The answer is simple, but very few people can explain it. Gnomon was writing a guide entry on it a few months ago.

Professor Gregory wrote a whole book about it. "Mirrors in Mind".
Here's a review of the book from American Scientist magazine: http://www.americanscientist.org/bookshelf/pub/mirror-mirror

I got a tremendous kick out of one of Lewis Carroll's illustrations, of a maze in a park, where by means of inserting one bridge over the path, where the maze crossed itself in a brief excursion through the third dimension, Carroll made it impossible to solve the maze by the 'keep one hand on a wall' method, which always works with a strictly two dimensional maze.

Coelacanth, it's a perfectly serious question, and I thank you for your perfectly serious response. I will contact Bristol uni, and report back.

Well now, Groob, I do hope - and no doubt some others are hoping - that you'll let us know about it -
- when the time is right, of course.

How can you be sure it's a *new* optical illusion? I think it's somewhat self-aggrandising to declare it new just because you haven't seen it before...

I was wondering that - like 'discovering' gravity?
Devising a new illusion is possible perhaps, although how would you check no-one had previously noted it? I don't imagine they are patented.
