This eye-bending perception trick is pretty popular, but as usual, Ugmonk made this shirt awesome by doing the design cleanly and choosing the perfect colors. It’s a very simple design, but Ugmonk gets the weighting of the borders and everything else perfect. I also love the white lines on the mint shirt (I think that’s the proper color nomenclature). So yeah, this is just another clean, simple, and awesome design from Ugmonk.
You can purchase Perception for $24.00 from the Ugmonk store. They print on American Apparel blanks, and as I mentioned, I believe the color of the blank is “mint”.
