Kartell La Marie by Philippe Starck set selector

Because I want to buy a set of four Kartell La Marie chairs and there are five colors to choose from, I want to know what the options are. So given the number of chairs to buy, this script generates the possible combinations. To see how the different permutations look, the chairs within the set are drag-and-drop sortable, and the sets themselved are also drag-and-drop sortable. A higher amount might take a while to generate, and more than six gives so many options that this generator doesn't help much in that case.
