We visualise this design as the flow of a conversation between two people. The shapes and colours move left-to-right and right-to-left and the harmonious colours and rounded shapes suggest broad agreement with the solid white tiles being the pauses. Every once in a while, though, there is an angular AL1 tile, a spiky, pointed comment perhaps, or an expression of frustration. Should the other pick up on it or let it pass? That part of the interpretation is up to you!

Tiles: ALL, AL1, E4 and E5
