Grid Optical Illusion Design T-Shirt
Lingelbach Scintillating Grid Optical Illusion The scintillating grid illusion is an optical illusion, discovered by E. Lingelbach in 1994, that is usually considered a variation of the Hermann grid illusion. It is constructed by superimposing white discs on the intersections of orthogonal grey bars on a black background. Dark dots seem to appear and disappear rapidly at random intersections, hence the label "scintillating". When a person keeps his or her eyes directly on a single intersection, the dark dot does not appear. The dark dots disappear if one is too close to or too far from the image.

The Shirt itself is a really nice, high quality material. Its quite thick and the colour is spot on whats in the pictures. The print is 100% what I wanted and the overall product is amazing. I ordered a 2XL which is already pretty big, it came a lot larger than I expected so next time i would order a smaller size, but thats down to me. It came just in time and the staff were super helpful in speeding up the shipping process for me so it would arrive on time. The printing turned out better than i could've imagined. I was very skeptical at first and wasnt sure how it was going to look, but it honestly looks awesome. So happy with it :)
