I came across this post on Digg that lists 5 technologies that in the future will change the way we go thru our normal shores. All from the way you interact with games and applications to the white board you use to teach classes on.
From the 5 selected technologies, there was one that actually caught my attention, although I encourage you guys to go check the other four. This technology, called Assist Sketch Understanding System, uses an electronic white board along with a piece of software that simulates physics acting over artifacts you draw on the board.
The following is a video of a professor from MIT that shows this technology live.
Kind of cool, isn't it? Ok, so you now wonder what kind of application u can use as to simulate something similar, well I found as well that Microsoft has this application called Physics Illustrator (PI) that pretty much does the same thing, just without the white board.
PI is a motion simulator for the Tablet PC and ships as a Tablet PC Power Toy (although u can download the source code from Microsoft Research and compile it so that it can run on any .Net supported OS).
PI allows you to draw two-dimensional bodies, connect them in various ways, and apply forces, then watch as animation makes the bodies move, collide, and interact.
Update: Googling around I found the following resources that I thought might interest you guys:
