I saw a picture of a painting that had lots of curved arches. I liked the idea and set about making a series of different sized arches with flat bar and junk. When it came to assemble I thought hard about whether to keep it mostly 2-D or move some of the arches to give it more of a rounded form. I so decided and the arches more or less made a fountain form. There actually is a rainbow fountain in Seoul but this is more just a rainbow of shapes within an ordered frame.
