Colored Lines 15xp

Simple Space Ball  15xp

This (and all the following challenges) relies on the modulo operator (%). Think of grade school math. Back then (at least in my youth) when you divide 9 by 5 you get 1 with a remainder of 4. The modulo operator gives you the remainder.  So 9 % 5 = 4 and 14 % 5 also gives you 4 because 14 divided by 5 is 2 with a remainder of 4.

 

I also use stroke(r, g, b) to change the color of the circle border. and strokeWeight(x) to change the thickness of that line.
