Near my street there is a park. The temperature outside today was way above average for this time of year. I took a walk, constantly pointing my camera towards the sky. Then I sat on a bench, soaking up the February sun. Above grass, there were four tiny little insects that moved up and down, up and down, like little yo-yo toys. Like bouncy balls in slow motion, but in steady rhythm. Only up and down, in perfect vertical lines, not forwards or backwards or in circles. Like little spiders on a trampoline.
