RABBIT is a plug-in for McNeel’s Grasshopper that simulates biological and physical processes.

Rabbit provides an easy way to explore natural phenomena such as pattern formation, self-organization and emergence. The add-on gives architects and designers the opportunity to integrate these models of organization in their own designs.

Cellular Automata

Cellular automata are simple computer programs that can generate complex behavior. Cellular Automata have been widely used to model city growth and urban sprawl.

RABBIT provides an easy way to run multiple types of Cellular Automata straight into Grasshopper & Rhino.

Branching Structure using Rabbit by Morphocode


L-systems have been extensively used to model natural phenomena and plant growth. They find application in generative urban models, in generative art and music.

RABBIT can create 2-D and 3-D L-systems using the special Turtle & L-System components.
