In his latest article on O'Reilly Digital Media, dekeBytes: A Taste of Vanishing Point 2.0 in Photoshop CS3, Deke McClelland says, "The Vanishing Point filter was one of the way-cool additions to Photoshop CS2. And it's gotten even better in CS3. Now you can connect non-perpendicular surfaces and wrap an image around multiple surfaces at a time."
He shows exactly how this works by melding an image around a virtual DVD case. Sample files are provided so you can follow along. It's a good tutorial if you're interested in learning how to use the Vanishing Point filter.
