Failed for unknown reasons three times in a row. Thinking it was noise on my mouse scrollwheel, I took the batteries out of it. I'm gratified to learn this was unintentional.
This said, the site is really, really making me think about moving back to Puerto Rico.
Nice idea; made me realise how few "do nothing" breaks I take in a day...0. I'd probably like to use it throughout the day if the problems in Chrome were ironed out.
Failed for me every time before I even did anything (Chrome, Vista). When I changed tab, and then came back without mousing into the viewport, the FAIL message didn't appear...but neither did the clock count down.
