For what it's worth, this board is for Macro and Still Life. Up until a year or two ago there was really no place where Still Life fit in. After being chased off of other boards for posting such drivel and some whining and crying from me, Still Life was added to this board.
I would consider your image to be a Still Life so it fits right in here.
But are there really still alive? A philosophical question for a whole different time...
Anyway, I don't know who invented purple potatoes. Must have been trippin'. I never saw purple ones when I was a kid, but wasn't like we had fancy stores back then either.
