Stochasm is an app for Mac that makes art out of physics.

Stochasm does a simulation, based on physics, right in front of you. How it evolves is random, yet controlled by the kinds of ingredients and rules you put into it. You can also interact with it or change it in real-time. By tuning how the simulation reveals itself to you, through colours, transparency, and shadows, art is created.

Here’s how it works:

• Create your canvas (a system) and tile it with pixels: distinct squares of different colours (types). Pixels are your building blocks.
• Define the rules for how pixels move and interact with one another on the canvas. For example, you can tell pixels to transform from one type into another type, to cluster, or to separate. You can tell them how often they obey a rule, compared to other rules you’ve defined, and also if they need cooperation from nearby pixels to carry out their action.
• Run the simulation, and watch it evolve before your eyes. The more types of pixels you add, and the more complex the rules, the more elaborate the simulation will become!
• Interact with the simulation in real-time by drawing pixels with the mouse, or changing the rules at will.
• Tailor the colour, transparency, and motion shadows of the pixels to make your simulation look exactly as you wish.
