His personal site, Schillmania!, is an impressive mix of web design, funky scripting, detailed interfaces, mixed-media presentations and utilities all centering around client-side technology. But what I'm most excited about is Scott's implementation of the arcade game: Arkanoid. Not only has he re-created it with all original levels, he has also implemented an awesome level editor with which you can create your own levels and save them for others to play.
The interface is slick and simple, and yet looks more like an application program running than code in a browser window. His excellent use of sound enhances the experience without being overbearing. So, do check out his work, whether you're into games, design, or client-side programming.
