You might be interested in these pre-Gridcosm static grids then. The "engine" behind them was a meatscript running in a human bio-s.

The basic script of Gridcosm could be used to create a stand-alone grid-engine. I think it would be a worthy conversion. Perhaps we could have more than one grid going simultaneously. I'd also like to see a grid-project built with tiny squares (21x21) with an online JavaScript or Flash based interface. Pixel-by-pixel.
