I´m watching a small gnat wander across the screen of the internet terminal in my hostel in Pisco. I´m pretty sure its movement is constrained to moving in one direction for a finite unit of distance, at which point it randomly changes direction. At each change in direction it appears to be constrained to turning straight, forty five, or ninety degree angles, as if it were navigating across a piece of grid paper.
I think it might have flown up my nose.
no. there it goes again, Its actually quite remarkable.
