More pixel art inspiration from The Art of Computer Programming (volume 4A). These are Gray Codes, different ways of changing a binary value such that every value is visited just once, while also ensuring that only one bit is changed at a time.

I was thinking it could make for a fun little interactive piece to have something cycling through all combinations of its lights following different Gray Codes. And I'd been meaning to do something with a stack light/tower light (used on big factory floors to signal machine states like "error" or "running low on parts") since they're so visually iconic. So I grabbed a cheap one off Ali Express to play with. I wish it had more tiers, but any past 5 get very expensive very quickly. I'll keep an eye on ebay to see if some turn up, but this will do for now.
