Group 4 - Static image

This is quite simple but required me to work on my very poor maths skillsâ€¦ the use of functions helped a lot to structure the code.

Basically it's just a checkerboard in the background , and circles of various colours which are mathematically placed into a bigger circle at the centre of the image.

there was an idea to try to put Equilateral Triangles but could not figure out the math formula behind it to repeat it.

there isn't much else to say about this other than what victor has said. it is a simple static image.

really nice response to the brief, a big circle made out of little ones simple but effective. Well structured code too.

distinction.
