I really enjoyed using this pretty simple code. My approach to the task was a little different than you might expect, many people did a variety of random colours, I decided to do a greyscale colour palette, and have the circles a little bit smaller than what I saw from other people. I thought it gave it quite a sleek look, especially on the module of technology, I thought it fit well. I used PPMonumentExtended for similar reasons, very sleek and quite technological.
I gave this many different attempts but settled for this one, it might be less colourful and more 'boring' but I really liked it and thought it fit the module well.
