On Saturday we went to the O2 arena to try and see the Red Bull Air Race; but of course we were too late for some tickets. We did see some action from afar tho, some pretty amazing moves as the planes flew around (the photos don't do it justice!) At the nearby park there are some young trees planted in perfect grids and trained to be perfectly straight. I find the play off between perfection and nature fascinating, like how perfect and symmetrical leaves are, and yet how nature is so chaotic and although it's symmetrical it's never quite perfect. Or a very straight tree trunk, but with big knobbly bits on it.
