Wayfinding

I would really like to do something like this when creating my own wayfinding but I would worry that people might take it as a slight on their intelligence. I think that it would be really nice to incorperate a sense of art in the wayfinding, for example if we did end up having flower images on the walls to somehow have this in the wayfinding.
I also wanted to think about ways this could appeal to boys, and Banksy sprang to mind. I think that we could use his urban style in wayfinding, to make it seem less aimed at girls, and also to give a youthful feeling to the school.
