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.
