generative-art

I have a generative art app, and I'd like it to draw as many cycles as possible each frame without reducing the framerate. Is there a way to tell how much time is left until the screen updates/refreshes? I figure if I can approximate how many milliseconds each cycle takes, then I can run cycles until the amount of time left is less than the average or the peak cycle time, then let the screen refresh, then run another set of cycles. If you want your app to run at N frames per second, then you can draw in a loop for 1/N seconds*, where N is typically the stage framerate (which you can get and
