It's Blender in scratch! (well, kind of. It's a 3d CAD but that is all that is the same about this software and blender) It is a 16x16x16 grid with voxels. Eah voxel has only two attributes: Color and Position, which you can edit and draw in the panel to the right. (Yes, that's right, you can make minecraft thingies with this)
It kind of takes a little while to finish a drawing. Use turbowarp for a smoother experience.
