Semiotic influence of traffic lights. Green = go, red = stop. This is a very ingrained idea, at least our culture. We are exposed to it from a young age and failure to read the signs and follow the implied signification can be fatal.
Idea - traffic lights in a gallery that respond to the viewer's distance from the work. Stopping them from approaching….would it?
Point to note - in my work I am very interested in what the responses are, even if I don't see them. I need to take this into account in the production of my work, I can facilitate certain responses.
Impose a reaction?
