I (think) there also used to be a ropey frame for building with stone (flagstone, cobblestone, other??) in like alpha 5-ish?. You'd lay out the frames, and when you "built" them they'd visibly fill with stone...in layers. Like 4-6 layers to complete the block if I remember right. So...if you were building a wall, and put 10 of these in a row, you'd slowly raise the height of the wall as you clicked each frame. Kinda' immersive.
