Zu Chongzhi’s estimate

This shirt tells the world “I R square”

e^(i*pi)+1=0: The coolest-looking equation ever!

booya. in for one.

This is the first derby shirt I have ever purchaced. Im fucking excited!

Who the heck is [–1p`bil ?

I got my piece of the pi - Second shirt.woot purchase for me!

Now we wait for the person who always seems to complain about “another asphalt shirt.”

I don’t think this shirt would look right in any other color. Kudos to the designer and poo on you asphalt color haters.

It’s never too early to start shopping for Pi Day presents. March 14, 2011 is just around the corner!

In for 3.1415926!

(That’s an exclamation point, it’s not pi factorial.)

Woohoo! I’m so glad to see this today! I’m looking forward to wearing it. Thanks for all the support everyone!

Indeed. I was kind of hoping the clockwork crow would win buy hey, nothing like a little pi.

Thanks, woot. Now I can finally pick up girls in my calculus class. Chicks dig this. Eat your heart out, Shakespeare!

Awesome shirt. It is well deserving. Congrats!

You always have to have dessert after a long woot-off…

Darn. I was hoping you’d tell us what happens when you take the factorial of an irrational number.

You get slapped in the face by your calculator.

I think they should print the whole thing. Is that too much to ask?

I would have bought one if it had been on a Pumpkin colored shirt.

I don’t like math but I do like shirts with large numbers printed on it.

Psh. Some of you need to get a Life (of Pi).
