Controls
PC:
Use mouse to drag mass points around
Press any key while dragging to fix the position
iOS:
Use simple touch moves to drag mass points around
Use the pinch-gesture to adjust the spring length
The acceleration sensor determines the direction of gravity
(lock screen orientation for that to work properly)
