Math - Cartesian Bear: Witty s-f & tech t-shirts

Math

Shirts and household items that appeal to the math lover in all of us.

A giant Greek Pi symbol, with rainbow shading, and the number pi (3.14159...) in black filling the symbol. Designed especially for Evan, but it's a great design for anyone who likes pi and rainbow colors.

Evan loves the number Pi, and he also loves bright colors. His mom asked me to design a shirt for him — this is the first idea.

A giant Pi symbol, filled with the first couple hundred (or so) digits of Pi. The digits themselves shade from purple at the outer edges of the pi symbol to orange near the center.

Evan's Pi 2

I thought I'd try a second brightly colored Pi design for Evan ... he can choose his favorite, and so can you!
