## lissajous figures

October 22, 2009by Joshua Sugiyama (jds08)

enter the x and y values (ratio is important), then phase, the RGB values

call: (lissajous x y phase R G B)

After the “better draw”, place this!

(define lissajous (lambda (Horizontal Vertical phase (Red 0) (Green 0) (Blue 0)) (show-window) (for ((t (in-range 0 1000))) (let ((y (+ 230 (* 225 (sin (/ t Vertical))))) (x (+ 230 (* 225 (sin (/ (+ t phase ) Horizontal)))))) (ellipse x y 12 12 Red Green Blue 1) (sleep/yield .00001)))))
