This was created for the Georgia Tech Graduate Student Council's Pi Day Celebration in 2025 and won the award for "Best Overall." I was inspired by the definition of pi as a ratio of the circumference and diameter of a circle and fractional approximations of pi. The circle on the poster contains several diameters, each broken into a number of pieces. In the bottom left, there are 3 pieces of the diameter in one piece with the remaining portion of the circumference. In the bottom center, there are 9 pieces of length 1/3 of the diameter, plus the remainder. On the top of the poster are 47 lengths, each of length 1/15 of the diameter plus a very small remainder. Finally, along the righthand side, there are 21 pieces with length 1/7 of the diameter, plus the remainder. This remaining piece of the circumference can be seen to be almost the same length as the other 21 pieces, providing a visualization of the approximation of pi as 22/7.
