I'm looking for a word that means or connotes bringing together disparate things to make a harmonious whole. I'm gathering a group of artsy cratsy folks to do collage and mosaic, both of which attempt to make a beautful new thing out of bits of other unrelated things. So far I've got Synthesis, Concretion, Amalgamation or Conglomeration, but I want something less hodge-podge-y and maybe a little obscure. Isn't there some word from philosophy or rhetoric that would be appropriate? Thanks, you clever AB-ers!
