Steel is written in ASCII code running down the wearer's back on this soft, comfortable t shirt. The computer term, backbone, gives rise to this shirt design that celebrates strength. It was inspired on a shirt that was worn by a golfing legend. ASCII code was chosen for its numbers to reflect what looks weak can be the strongest. The 3 large 0s reflect the angel number which means starting a new beginning. Our shirts are great gifts for computer programmers, gamers, IT professionals, students and computer science teachers. The shirts have funny or inspirational messages to celebrate the wearer.
