TwTeX - LaTeX equations for Twitter

For all those times you've wanted to tweet an equation! Ok, so that doesn't happen very often, but now you can! Just enter an equation in LaTeX (x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}, for example), and you'll get an image and a Twitter-friendly URL to paste into your tweet. Yes, the target audience is small, but feedback is welcome!
