Gravity by Bill Stewart & Tracy Elmore
©1990-92 Berkeley Systems Inc.

Part of the After Dark 2.0 collection.

Though essentially replaced by later "marble" based modules, Gravity still retains some old world charm of the original After Dark release. Though not as flashy as Flying Toasters, gravity perhaps epitomizes what was enjoyable about the After Dark series. Each module was a mini-show of seemingly random events that could be customized to an extent. Not knowing the trajectory of each ball released was part of the fun. See, we were easily pleased and much less jaded back in the early 90's.

I've had some inconsistency with regard to the speed of this module with it sometimes running too fast and other times running about right. I've found some success using the options below.

GRAVITY (tm) demonstrates Newtonian gravity with bouncing balls.

Original idea by Bryce Fowler.
Sound by Rob Gale.

Choose 1-7 balls with the "Number Balls" slider.

Use the "Size" slider to set the size of the balls.

Check "Clear Screen" to clear the screen between each set of balls.

To hear the balls bounce, use the sound control (if sound capability is available)

Works under Windows XP & Vista in greater than 256 colors but can be too fast.
