This free Java applet lets you have an image rotate on your site in 3D. It takes a 2D image and spins it around it's X, Y, or Z axis as if it were a 3D image.It's great for logos on a site, or for general pictures that you want to spin. The applet can be linked to a file and it works with frames....
