If you look at a British £2 coin, you’ll notice there’s a motif in the design of one of the circles that shows a series of interlocking cogs. When the coin was originally launched, the Royal Mint declared that these cogs represented “the evolution of technology from the Iron Age to the internet”. Another thing you’ll notice if you look carefully is there are nineteen cogs, an odd number, all interlaced, thus any attempt to use this mechanism would lead to its snapping and spraying bits of cog everywhere. (Unless it were on a Möbius strip, supernerds.) This is the sort of thing you’ll become expert on after playing a Cogs for a while.
