This commercial for an energy drink features a paintball machine with 840 barrels. It fires a single volley with different colors to produce, in just a second, a image through a stencil. The action starts at 0:35.

As for the video clip, I have so wanted to do this.
From what I understand, the advantage of RISC over CISC is in it's computational speed, but CISC provides more flexibility which is why CISC is used for Central Processing Units and RISC is used for more specialied processing tasks, such as the North and South Bridge, the GPU and the chip inside your toaster.
Thread handling techniques differ from real parallelism in that with thread handling only one task is ever performed at the same time, much like the first robot operated by Adam and Jamie. Except that robot only has one task to perform, if it drew two pictures and shared it's processing time between them, that would reflect thread handling. Parallelism is an aspect of multiprocessor computers, but even that is a psuedo-parallelism as all the instructions must filter through a time-sharing processor first that allocates portions of the task to other processing units. Much like some networking protocols.
This is vastly different than the parallel processing which happens in the brain, which is more akin to the second robot in Adam and Jamie's presentation. I could be wrong though, it's been a while since I studied computer processing technologies.
