Random collection of game elements, primarily physics based stuff.

Most importantly:

• Gravity grab dynamics: grab/attract/drop/throw objects
  • 1st-person gravity grab dynamics
    • similar to the gravity gun in HL2
  • 3rd-person gravity grab dynamics
    • the cursor can attract and drop objects like a giant magnet
• animated stairs
  • Stairs widen when approaching, walking them
  • Stairs contract again when too far away
• 3D planet gravity: hug the surface of a sphere (still a bit bugged)
