Pi Cards
Perfect for your mathematically inclined friend! Three (3) blank ivory greeting cards with envelopes. I screen printed a navy blue distored pi symbol onto the front of each card. It is an original and handmade design by me!
Great for any occasion. ~4x5.5"
What's so cool about Pi? From wikipedia...
"Pi or π is one of the most important mathematical constants, approximately equal to 3.14159. It represents the ratio of any circle's circumference to its diameter in Euclidean geometry, which is the same as the ratio of a circle's area to the square of its radius. Many formulae from mathematics, science, and engineering involve π."
