Apparently, they were known in some countries as 'bubble' cars, though I can't help hearing the tune to the Beatles 'Yellow Submarine' when I look at this. It's actually a two-seater BMW Isetta 300, sold between 1955-1962, displayed in the BMW Museum, Munich. I learned recently that an Italian company has redesigned the car to be more steamlined and the modernised version, powered by an electric motor, has gone into production.
A seated abstract from inside the Olympic Stadium, Munich. I find scenes like this with a pronounced symmetry often work better when there are subtle breaks in the symmetry. Symmetrical perfection seems artificial and contrived, as if a computer algorithm is the creator. There are subtle natural asymmetries present in this image, for example, just above the centre and to the right the seats become slightly misaligned. I capitalised on this by slightly adjusting my angle to have the extreme right and left of the foreground frame differ slightly.
