The same model appeared six times on the panel. There were other models that also made multiple appearances. I don't know whether architects are just cheapskates who won't buy more models or whether there's a psychologically-proven reason for re-using them to trigger a subliminal sense of harmony or something. Most people probably wouldn't notice that the same models were being re-used.
Didn't work on me, though, architect. Sorry.
