Concept 1: Semi-abstract composition images, full colour with single word (all words end with “ation� to give a flowing syntax from board to board). Riley stripe on top of images (crucially all of these images are of the right size/resolution for these boards and free for us to legally use). metal posts are raw metal.
Concept 2: Semi-abstract composition images, full colour with single word as above. No Riley stripe on top of images - instead, metal posts are coloured in Riley colours with vinyl or paint (easily obtained and applied), with black ends.
