Can I play? I wrote a RK4 gravity simulator a while back in WebGL, but my main goal at the time was to find a way to visualize gravitational fields, so its nowhere near as interactive or user friendly as your implementation. I was trying for the effect you see in high school physics videos. My approach was to use a plane geometry mesh and apply a vertex displacement shader, but never quite got it to look or perform how I wanted. http://programmarchy.github.io/gravity http://programmarchy.github.io/gravity
