1.6 Megahertz per Pixel: TMDC6
TMDC Organizing writes "The sixth pseudoannual text mode demo competition is on. The goal is to make cool audiovisual demos that run in an NT console. Deadline for submissions is 12.12.2003 (Slashdot has covered TMDC before). An invitation demo and all the entries from two last contests are available."
The FAQ has some static screenshots.

The last time this competition came up, I got to wondering what's to stop you from doing "bitmapped" text mode? Standard 80x25 text mode is 30 KHz ie. 30,000 lines per second, each 640 pixels wide. That's about 24 million pixels per second. These day we have multi giga-op processors, and interrupt hardware can't be far behind (?).
Simply set the screen to 80x25 space characters then trigger interrupts a bit before each pixel and change the background color. Hey presto, 16 color bitmapped mode. Then use temporal anti-aliasing to yield even more colors. Kudos to the first person who makes a X driver for this mode.
Sure, this will eat a lot of CPU time, but that's what this sort of competition is all about.

One thing that has always bothered me about the demo scene, is their lack of openness. It's very hard to come across the source code of a demo, or even just a description of how it was done.
It's frustrating for multiple reasons. First, because it's harder for newbies to learn the art, and second because after some time, demos that were real pieces of art, Second Reality for instance, are pretty much unrunnable on a modern computer. And this is truly sad.
