Just had this mad Idea of using this new 99$ Open-Source gaming console called OUYA for rendering.
Here’s some further information on it if you don’t know that project already
So that device has a Tegra 3 Quad Core with 1 GB of RAM which sounds quite decent for rendering.
As that system runs on Android blender shouldn’t be too hard to get running on it, as we have already seen blender running on several android tablets/smartphones.
What do you think of using a few of these little cubes for rendering?
