You can simulate gravitational field of one or more particles, or even inside quasi solid objects (with randomly 'constant' density). NOTES: -The more particles you put, the smaller color scale value should you use! -The particles slider isn't linear. -Setting a vector length value shows even the direction of gravitational force. -You can download the sourcecode for more options, like modifying the simulated area. -It don't calculate (yet) 3 dimensions, like a sphere, but Earth's density isn't constant, anyway, so it's not a realistic, just a 2D simulator. Maybe later I will add mass, motion, alignable and moving particles.
