Polyhedra stacking sandbox. No gameplay, beyond the fun of arranging space-filling polyhedra optimally (or randomly if you choose!).

How to use: WASD/QE to move the camera and right-mouse to rotate it. Left-mouse drag on the handles (purple spheres) to move objects - they will snap to 'compatible' handles elsewhere in the scene. Everything spawns at 0,0,0 - so start by dragging the first few objects away and snapping to new ones as they spawn on (otherwise the object will just move back to its original location at the origin if not snapped to another object).
