We are big fans of lighting cheat sheets, ever since with pulled our first one, featuring my former boss, which shows 24 positions of lighting for portraits. (Which was later nuked with a software creating a similar chart with 72 lighting positions using a 3d head scan from Infinite Realities).
Interestingly enough, a similar scan by IR was used to create the Virtual Lighting Studio an interactive chart that you can plug lots of lights into and position them anywhere. So as long as you don’t really care about expressions, hair or human interaction, you can light and shoot at the comfort of your living room. (Or make your mega lighting card cheat sheet)
