I am not even sure how I came across this site. A few days ago I found myself browsing Dan Phiffer's Web site and I have to say, it is probably one of the more innovative sites I've seen in a while.
There are some drawbacks, however: After visiting the site numerous times you kinda forget what you've seen and what you haven't. Subscribing to his feed is actually the feed to his blog powered by Tumblr. And, some of the links from the front page have no way of getting back without clicking the back button on the browser or hacking up the URL.
But what this site lacks is made up for by the fun of actually playing with it. Very cool. Pushing the envelope. Kudos.
