This is your visual system slipping on a banana peel. Be sure to check out the detail shot on the product page. In this motion illusion, the implied shadowing is not consistent with a single light source, causing dissonance in your personal wetware visual subsystem. Spurious motion is added when it tries to reconcile the implied shadowing of neighboring objects as your eyes wander over this confused state of affairs (hey, wait, we are not making any reference here to the state of politics in California or anywhere else, really, we're not).

In addition to the rolling motion effect, which people see to varying degrees, there is also a more subtle illusion: very fine and fleeting grid lines seem to appear between the pattern of "stamps" as you move your gaze over the full size image. These lines are another tiny clue via brain bugs as to what the visual cortex is up to. Obviously further tee-shirt-based science is called for in the area of illusions.

Thanks to the Libre Map Project for making wonderful SVG outlines of the great state of California, and all the other great states, available online.

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.
