Prototype lab

Rough versions. Play each for five minutes on a phone and note which ones you restart without thinking about it.

TurnfallDrop a block, then the whole box turns a quarter and everything slides to the new floor. Tipping PointNumber blocks land on a seesaw. Equal numbers merge. Too much weight on one side and everything slides off. Loop YardLay track pieces. Close a loop and a train runs it, then the loop clears. Full ShelfSlide books onto shelves. A shelf filled exactly, with no gap, snaps shut and clears. SprinklePlace sprinklers so every plant is watered exactly once. Twice drowns it.
