Ideal in times of corona: art with no fixed route, no entrance gates and no opening hours. Luckily, Utrecht has enough to offer in this respect. Such as the mural on side of the Spice Monkeys restaurant on Oosterkade, close to Vaartsche Rijn station. This design created by De Strakke Hand artists’ cooperative is an ode to the Utrecht physicist Leonard Ornstein (1880-1941). He and Professor George Uhlenbeck (1900-1988) described the so-called ‘random walk’, in which an object makes a series of random movements. A drunk doesn’t walk in a straight line, for example, but follows a process of randomly stepping forwards, sideways or even backwards. Fate dictates the direction. This is an example of a random walk.
