QJ.net reports that "some hackers have announced that they've discovered a way to access the 3D contexts on the Graphics Processor Unit of the PlayStation 3. If what they say is true, then this will allow homebrew developers to create their own 3D applications for the console.
CNLohr posted a video on YouTube of the PlayStation 3 running some code in Linux. Allegedly, the hypervisor is talking with the nVidia RSX video card of the console to render the three animated quads in the foreground and the triangles in the background.
According to CNLohr, the demo being used is a modified version of IronPeter's libps3rsx from ps3dev.org. For those who want to try replicating his setup, the PS3 is running using a patched 2.6.24 experimental, unofficial kernel on Gentoo Linux".
