Happy π Day!

I honestly love some good math (I'm a topologist at heart), so it's my pleasure to announce a Pi Day Sale at my Rocklawn Arts Zazzle store.

Get 12.56% OFF everything in my shop until 11:59pm PT March 14, 2011 (that's today, considered "Pi Day" because the date is 3/14). The 12.56 comes from 4πr^2 where r=1 (couldn't figure out how to raise the 2 to make r squared, but I think that notation is still correct).

Use coupon code: 314159265358

Cool, unusual photography FTW! Architecture, landscapes, abstracts, nature details, rainbow patterns and more! Customize a gift for yourself or someone special.
