Is there an actual link to this software.. searching for "interactive physics" doesn't really work.

That's funny - I searched for "interactive physics" and came up with several links including - http://www.design-simulation.com/IP/index.php

Ah. I found that, but it didn't look like the right thing to me Thanks.

These types of simulations can also be done with any major 3d creation package such as maya and 3d studio max. Fun stuff =D

The Ultimate Jello Simulator!

Awesome, I use this in my AP Physics class, great program, leads to much enjoyment =p

Now they are coming out with Physics cards you plug in your PCI slot to enhance physics engine calculations.

Beginning reminds me of XGL. I wonder if physics engines will also support desktop 2-D effects.
