Somewhere on the internet there is a video of a line of marbles rolling down a furrow traced in the mud. They change positions, choose different lines, hold back then dart away full pelt, apparently racing for all they are worth. Just when one has what looks like a winning lead, it stalls and another flies past. If you’re used to watching cycling, you could be forgiven for projecting certain assumptions onto it: this marble has been in the red too long, that one’s thought processes are fogged and it has made a wrong choice.
If you let it, it can become compelling.
