playing with Html5 Canvas – doing a control loop with thrusters (blue) and rotation control — adding in two fixed points which have gravity.
I’m using m/(r^2) here .. its not quite right, as the two objects are not orbiting each other. I can’t get it to orbit nicely 
I turned off the “clear canvas” bit so that the paths could be seen.
The red bits are drawing of the force lines due to gravity calculations.
