This week, I’ve come across a lot of sites with sunbursts, a specific type of lighting that’s popular with not just the Web 2.0 look anymore. You decide if they’re crucial to the design or not.

Backgrounds are so called for a reason. They’re meant to support and complement instead of attract and distract. This week’s featured sites, however, provide a whole other level of interactivity and usefulness to backgrounds. You decide if they’re a good idea or not. Either way, they’re interesting concepts that can only be executed on the Web, so, enjoy!
