In case anyone was curious, I have made a bonus video about how I produced the scrolling numberline of prime gaps. Spoiler: it was all done in a spreadsheet!
This video also reveals some terrible python code I will not be releasing any other way!
But you can download the Excel file. I'm prepared to share that. https://www.dropbox.com/s/39795t4tfa54i6m/prime-number-line-LONG.xlsx?dl=0
