Arrhythmia.js, a new take on rhythm validation (eng.wealthfront.com)

Dude, this is sweet. Nicely done.

While I agree with the all the principles of having good vertical rhythm on page typography it has often been impractical to chase down and fix the offending markup and CSS. This appears to take a lot of the grunt-work out of finding and fixing the vertical rhythm issues on a page. Thanks, and keep it coming.
