Yevano:

The CCGPU peripheral is an addon for [[ComputerCraft]] which allows you to do [http://en.wikipedia.org/wiki/OpenGL OpenGL] operations within computercraft using [http://www.lua.org/ Lua]. The peripheral currently comes with two blocks: a [[#GPU]] peripheral and a [[#Monitor]] output device.

CCGPU

2012-03-17T23:53:40Z

Yevano:

CCGPU is a peripheral that provides a GPU and a monitor that can display graphics using calls to OpenGL. The GPU is run by setting its render code, which is stored in the GPU and then runs on the players' clients. Multiple monitors can be hooked to one GPU, as long as they are within a 16 block cube of the GPU. The GPU is connected to a computer on any of its sides, allowing that computer to use the gpu API.
