My thought of the day is the following…
If I had unlimited funds, I would buy out the outdoor advertising of every bus, bus stop and billboard (etc) for a week or two and place in this space nothing but white.
If someone were to ask me what it was all about, I would simply reply, “Nothing. It’s about nothing.”
If we wanted to get wanky then we could call it “zen-vertising”.
I would then go around and capture what people would write or draw in its place. Or a before and after of their faces to see if anything changed.
