I Sign My Tracks Tee
The holes in the Curiosity rover's wheels spell JPL in Morse code, so it prints the lab's initials into the Martian soil with every turn.
What you're wearing
The pattern also helps the team measure how far it has driven (NASA/JPL). Drawn in the manner of frottage, crayon rubbed over paper laid on textured things: riveted plate, perforated sheet, honeycomb and wood grain. The paper is the shirt. Front print. Unisex fit, 100% cotton.
