Your piece of paper example caught me a bit off guard. It sounds pretty similar to a quine ( http://en.wikipedia.org/wiki/Quine_(computing) ). I think that the same thing is possible with a demo - write the code to render a piece of paper from an array of letters, and put that part of the source code into the array.

Yeah I'm wrong. What I had in mind I guess, is take an existing very impressive 64kb demo, then do this. That might be much harder, but not necessarily impossible in theory.

A far better argument for me to have made is that it would be impossible to have a 64kb demo which models a surface on which is printed the source code of all 64kb demos written since the start of the scene decades ago. Of course, if equations that describe all of reality are discovered and fit in 64kb, and the graphics card contains a universe simulator, then maybe it's possible.

Such a demo would be possible, it would just take an infinite time to run.
