Tiff is a typeface diff tool that visually contrasts the differences between two fonts. I had the idea of creating such a tool to help me compare two fonts while learning about typography.
The app is currently running at http://tiff.herokuapp.com
At this point, Google Web Fonts serves as the only source of external fonts for Tiff. However, I'm working on including more font sources.
Since the app uses some features only available in HTML5 and CSS3, use recent versions of modern web browsers for maximum compatibility.
Thanks to my friends Michael Choi and Riobard Zhan for offering generous advice.
Thanks to Mark Brown (@markbrown4) for the font aligning code.

Any feedback is appreciated.
