That Prime Number Spiral Thing

While at Pasadena City College, as I was developing my interest in mathematics, I noticed an intriguing pattern while experimenting on my computer. I posted about it on Math StackExchange, specifically asking why prime numbers seem to form spirals when plotted in polar coordinates. I've licensed the polar plots I created under CC-BY 4.0.

I was pleasantly surprised one day to discover that 3Blue1Brown had featured my question in one of his videos. Grant Sanderson does a great job of explaining the deep mathematics that I stumbled upon in this video. In the process, he immortalized my afternoon of procrastinating. Thanks 3b1b!
