Ready
Ready is a program for exploring continuous and discrete cellular automata, including reaction-diffusion systems, on grids and arbitrary meshes. OpenCL is used as the computation engine, to take advantage of the many-core architectures on graphics cards and modern CPUs. OpenCL also allows rules to be written in a text format and compiled on the fly. Ready supports a compact XML-based file format so that images and rules can be shared easily.
Ready supports 1D, 2D and 3D data, as well as polygonal and polyhedral meshes.

We're working on the next version, which includes two new features:
- Import of images, so you can use a photo as the initial conditions of a pattern
- Export of a sequence of OBJ files, for animating a 3D mesh.
For now these features are only in the 0.7.2 release or later.
More details on the releases tab.
