Early simulations with GravityLoops

This article describes the early development stages of GravityLoops, a gravity simulator written in Interlisp and LOOPS. The author shares their progress in getting the simulation to display a simple two-body system (like Earth and Moon) after 180 simulated days. Key technical details include implementing a simulation loop with an offscreen buffer, tweaking methods, writing a demo function, and fixing bugs. Future plans involve improving graphics, animation speed control, refactoring interclass dependencies, and adding a user interface. The article is relevant to IT/technology as it covers programming, simulation, and software development in a Lisp environment.
