Yeah, pretty cool stuff. Optionally generated things can be very useful indeed as starting seed to a large work, inspiration and assisted workflow. However, imo it's pretty much the last point on the list after getting everything else right about a craft. And I think there's still a lot left to be done right otherwise--for me anyway, the more I get right, the less it seems necessary, whereas most of all the voxel space often very much depends on it, because of the incredibly huge workload; but I think priorities have been not what they should be. At any case, watching things generate is immensely satisfying for a coder to toy with, so I'll have my own stab at this as well at some point, for the hell of it.
