Still waiting for the Feynman Lectures on Mario Physics to drop :-).

I thought this was a great way to practice data analysis, I wonder if you could correlate it with registered trademarks from Nintendo. Specifically do they always trademark the whole name? Or are there specific 'Mario' trademarks in the specific color scheme.

The other thing that I pondered was if this was a scheme to detect/delay counterfeiters of Mario game cartridges. Back in the day there were a lot of dodgy game carts on the "used" market. Coming out with a different color ordering would force the counterfeiters to take some time to change their artwork before shipping their goods.
