You may have heard of Markov chains, but have you heard of the Dérive? From the mid-1900s French Situationists, this practice of exploration found its roots in subversion of a city's terrain or subversion of the intention of the things within it. The game starts with a prompt such as "follow yellow things," "take two rights for every left," or "follow the birds." Rather than going about your business, from chore to errand, or along the paths laid out for you, or in a line from A to B, use your prompt to guide your exploration and open your eyes to new aspects of the world around you.
If you discretize each place or moment as a node, and you consider how your prompt together with the environment creates a probability distribution of the next places or moments you will encounter, with such openness to the prompt, you will be living in a Markov chain. This independence of objective and situation is the Dérive, to rid yourself of the habits, constraints, and inclinations of your day-to-day life.
So in this spirit, I spent 1hr this afternoon following the color yellow. As it turns out, in a busy city, there is so much yellow, you can rationalize any path you want to take. Yet, in pursuit of my abstract objective, my eyes were constantly open and searching for every yellow thing. I saw the world in a new light. What I can't rationalize is, and what I hate to include because it was a very sour note, I think I saw a homeless man attack a bird. Well, I found something yellow somewhere else as soon as I could. I took a path through my neighborhood I never have before. I took a train to where I've never seen before. I saw a hundred different people living in this city, some with sorrowful eyes, and some bright. Mine were filled with curiosity.
That was the best thing about it, to cast off the week, the goal, the journey, the past, to look with open eyes from a moment, and see all the possibilities. Consider it a type of meditation. A break from your destination. If just once in your life, cast off all that you know, and look at the world with new eyes.
