Realmac Software’s Clear to do application has gotten an enormous amount of media attention over the past few weeks. One publication said that Clear’s innovative, gesture-based UI “had the potential to change how we use our devices.”

But if you haven’t had the chance to try the app out, then it may be hard for you to see what all of the fuss is about. Luckily, developer Evan You has created an HTML5 replica of the Clear application so folks can give it a free test drive…

Using only HTML5 and CSS3 transitions, You was able to re-create the look and feel of Clear’s UI in only two days. The developer admits that it’s not 100% accurate, and there are still a few bugs, but the web-based app looks pretty close to the real thing.

Even though it lacks the character and fluidness of the official Clear app, You’s HTML5 mock-up gives you a pretty good idea of what it’s all about.
