Gravitation 2.0 (MX)

My own creation from start to finish -


(Flash MX) =)

Click and drag - create velocity vector.
(Hold space to use “push vector”.)

[]An awesome retro skin,
]Four modes of gravity: Fg=0 (n/a), Fg=k (uniform), Fg=k/r (partial), and Fg=k/r2 (complete gravity according to the Grand Unified Theory),
[]Optional air friction and walls, and
]Time control that allows full speed or frame-by-frame playback with one- or ten-frame increments.

I’m planning to add a secondary source of gravity to make dual orbits, etc. Any other suggestions? I might try multiple particles… we’ll see.
