Tensional Planet

This simulation is kinda like a weird jello surrounding a rock planet.  You can drop giant rocks on it, or highly dense satellites that will spin around it, or grab the jello surface and move it around.  Also, there’s wind, so you can make it push around away from your mouse.  The program is pretty extensible and uses my messings in spring physics as I learned in my Introductory Mechanical Physics class this term (actually, much of the code is copy-pasted from my term paper).
