Having worked with Superfrog for nearly 4 years as their artist/creative director, I have developed 3 different web sites for the band, along with a variety of marketing materials.

This site was launched in October of 2010 for their album "Call from the Moon". The site was designed to be W3C compatible using HTML 4.0. THe shell of the site uses extensive CSS to layout the images and links, and embeds the core of the site, a fully integrated flash interface, within the framework.

You can see the live version of the site here.
It has a mobile version as well which will load on handheld devices.
