My wife mentioned something about Spirographs yesterday, so I thought “hey – why not make one in actionscript”. Two seconds of googling found the formulas I was looking for (as well as a nifty java example), and about 10 minutes of coding had something up and running in Flash. Play around with the sliders and hit “draw” to create a little Spirograph masterpiece of your own. Speaking of controls, the first slider controls the radius of the fixed circle, the second slider controls the radius of the rotating circle, the third slider controls the offset of the “pen tip” in the rotating circle, the checkbox specifies whether you’re drawing outside of the fixed circle or not, the color swatch will let you select a color to draw in, and finally, if you just want to see the thing in action, click on the “Randomize!” button and see what you get. If interested, the whole script is below (I used bit-101’s minimal slider, button, and checkbox, and my own color picker, if you’d like to compile this thing): [crayon-603d09eeac60c450519195/]
