“The dynamics of composition… Yellow, red and (almost) blue flowers in a mixed assortment are constantly swapped and reconfigured until suddenly they are composed entirely of flowers of one color. The strangest thing about the progression is that its consequence is not obvious: in the lead up to the red arrangement for example, red flowers are added and removed apparently as often as the other colors. Like a conjuring trick, you are only aware of what is going on at the moment it happens and it is too late to try and track down the process that brought you there.”
