I have been working on a web-based interactive environment for creating 2-d mechanics problems (with bodies like particles,disks,boxes, forces like gravity, springs, linear & circular motors and joints like revolute joints and sticks etc.) and simulating them. Think Algodoo for the web. I think it's cool because nothing like this exists for the web. I recently gave a presentation at a Javascript conference in Bangalore on this: https://hasgeek.tv/jsfoo/2013-2/688-interactive-physics-simulation-in-the-browser-what-i-learned https://hasgeek.tv/jsfoo/2013-2/688-interactive-physics-simu... To see the demo, skip to 13:00 in the video. I haven't launched it yet because collision detection and response is pending. Hope to do it soon. :)
