Chunky Orbits

Get up-close and personal with Gravity.
Chunky Orbits is a simulation of free-floating objects in space based on real life physics. Each object in the scene attracts each of the others in a cosmic tug-of-war that we call Gravity. Toss out a few boulders and contemplate the wonders of the Universe.
This is not a game - more like a physics-based toy. Might even be educational. It certainly gave me a new appreciation for how Gravity works.
The simulation consists of a large empty area in deep space. You pilot a simple ship and are free to place new objects wherever you like. You can create several types of objects - boulders, white dwarfs, center stones, and absorbers. You might also want to add some trails to your boulders to track their paths. You also have a sparkly photon cannon that's used to remove objects, or to stir the pot with some kinetic explosions. :)
It's a big physics based playground. Create a random grouping of boulders and watch as they collect into larger, chunky groups. Launch a super-massive White Dwarf and observe how it affects the other bodies in the system. Create a small 'solar system' and see how many chunks you can get into orbit.
If you're interested in seeing the sim grow, please head over to the forums and offer some feedback or suggestions for new features while it's still in Early Access!
