Spirograph in Small Basic


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.

Image result for spirograph

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.
