New T-Shirt Design: Pulsar PSR B1919+21

[T-Shirt - Pulsar]I made this t-shirt for myself, but I figured I might as well try selling it through Cafepress.  This public domain image is a graphical representation of exactly 100 successive pulses from the first pulsar ever discovered, PSR B1919+21. It is also the image used on the cover of Joy Division's first studio album, "Unknown Pleasures".
