Just watch as a blue circle is slowly drawn using pen. Press space to clear the drawing. Press 'h' to hide the rods. Turbo mode not recommended--it goes too fast. Read below if you want to learn about the math behind this project!
Inspiration drawn from a Youtube video based on a similar principle. All coding is mine. The Irrationality of Pi Pi is a never-ending, never-repeating number. This can be observed in this project. The outer white rod rotates pi degrees faster than the inner white rod. This means that the two white rods will never occupy the same two positions more than once. After running for long enough, the space will appear to be completely filled out. This is due to the limitation of Scratch's pen size. If zoomed in many, many times, blank spaces would still be present.
