Lomography for Luddites

My first solargraph and yes, it's of the back garden. It was taken over a three week period and through the window and so suffers from reflections when the light was on in the room.
Obviously, each of those arcs is the sun's passage across the sky that day and each day is slightly lower than the last. The breaks are when cloud crossed in front of the sun. The missing lines were cloudy days... Get it?
