Description

substrate

A pygame port of J.Tarbell's processing visualisation, based upon the xscreensaver implementation by M.Kershaw.

Cracks appear and through them sand falls. As the cracks become more numerous a city begins to form. If you continue the disconcerting feeling of moving away will strike you, as the city becomes more dense and continues to evolve.

This implementation allows you to place your own cracks and save snapshots.

Parameters you may modify include:
Screen dimensions
Background colour
Crack colour
Sand colours
Initial number of cracks
Maximum cracks
Invisible cracks
Cracks the colour of the sand
Percentage chance of a crack being curved
Percentage chance of new cracks being connected to old ones
Maximum degrees variation from perpendicular for new cracks
Number of sand grains
Maximum sand range

Smiles

Great! Was it modeled on the cracked earth during the drought?

@ Chandler. Yes It is very chaotic. If you have any suggestions I would be glad to hear them.

very very cool. this conjures to mind complexity theory (how simple rules yield complex looking patterns) and demonstrates how simple it can be to make procedurally generated content that looks plausibly real (in this case, a city structure). this is exactly what pygame needs more of.
