The cliche says what you see is what you get, but sometimes what you see isn’t even there. In this scintillating grid variation of the Hermann grid illusion, opposite-colored dots seem to flash inside the actual dots as you move your gaze across the grid. The jury is still out on just what neural idiosyncrasy causes this effect. You can do your own experiments in the budding field of tee-based science by wearing this t shirt and using other people as test subjects. Obtain a willing friend. If that’s a stumbling block, rest assured they don’t have to be an actual friend, they just can’t be blind. In any case, assuming you have someone looking at you, without warning or preface begin to move your torso in a circular or swaying and slightly jerky motion and ask if they notice anything strange. Answers may vary. It’s not every day a tee shirt is a perfectly justifiable use of your lab’s grant money.

Unless you’re ordering black or white, we can’t guarantee that t-shirt and print colors will perfectly match the color on the screen. Your monitor settings may be different, manufacturers pass along slight changes in their colorways, and some colors, like light gray, are offered in styles from different manufacturers and therefore won’t match each other. We wish we could bring you samples of our designs, but we’re waiting for improvements to current teleportation technology.

The organic shirts run small, and they're a fitted style. You'll probably want to get a larger size than your usual. The classic men's crew neck, the women's v-neck, and the youth styles run true to size. Click the Size Chart link above to get lots of info.
  • Our organic shirts are a lightweight, fitted style in 100% ring spun cotton (that means they're soft!). Organic girl shirts are girl shaped: sleeves are shorter and sides seams are curved. The organic shirts run small. Depending on how you like your shirts to fit, you may need to order a size or two larger. Click the Size Chart link above for more info!

  • The men's classic tee is a heavier ring spun cotton with a looser fit. We print up to 6XL in this style!

  • Youth shirts are suitable for both boys and girls in a heavy ring spun cotton.

  • The women's v-neck is a medium heavy ring spun cotton and has 3/4 sleeves and a moderate vee.

  • We recommend machine washing in cold water with the shirt inside out; tumble dry on low. If you iron (wow!), we recommend turning the shirt inside out first.
