Description:
This PDA program is a spring and mass simulation, though you may wish to forget the physics and just play with it like a toy.
You can easily build a world of nodes connected by springs and then watch what happens when you give a pull here and a nudge there.
The program is limited only by your imagination and the fact that this is a PDA which stores your phone numbers, not your desktop machine!
The program has a few built in patterns that you can watch fly around the screen, ricochet off walls, and drag around as you wish.
Using the graphical editor, however, you will probably want to design and play with your own patterns pretty quickly.
Experiment with the interface or read the included help file which is also available at http://www.medcosm.com/pspringies.html.
