Have you played with Spirograph before? I loved this toy and played with it well when I was a child.
Challenge of the Month - March 2015 has a challenge to draw a Spirograph with Small Basic.
Graphics Challenge
- Write a program to draw a spriagraph picture.
It's very interesting that many kind of Spirograph pictures can be made. And I also feel fun to understand the relationship between radiuses of wheels and pictures.
At least, if r1 = r2 + r3 then the lines in the picture pass through the center. And r1 - r2 + r3 is the circumradius of the picture.
Let's have fun with trying to draw variety of beautiful Spirograph pictures!
Thank you litdev for this challenge and for the challenges every month.
