I have written a simple Cube Wireframe Renderer on the PPU. Just wanted to share it with anyone interested. You can grab the source here. And this is how it looks: This hasn't been optimized for anything though. I just wanted to play with the sample library and Mike's FB Utilities. The line drawing algorithm is scalar(bresenham). It just rotates the cube for about 15 seconds by 5 degress on each axis and then exits. Have fun.
