CubeSter version 0.3 has been released!
New things include being able to color the mesh using and image instead of just vertex colors. Also, if using an image, then you can use an image to generate the mesh and another to create the material. All nodes are created, they are just not all linked up, so custom node setups can be done easily.
The newest version can be gotten here, and specific details, examples, and other info can be found here.
