Some Notes On iTunes LP · Jay Robinson
"The iTunes LP experience is accomplished with HTML 4.01, CSS and JS. The interface feels very Flash-like, but there is no trace of it. The CSS animations are elaborate and smooth. ... As a music fan, and as a web developer, I couldn’t be more pleased with the new iTunes LP offering. If your audience is significantly Apple-oriented (e.g. a site about Mac rumors or a popular iPhone app) this proves that you can provide an incredible experience using only JavaScript and some proposed CSS3 properties."
