4th Dimension

I had an idea for this poster. If there was a way that the grey letters fell of or disappeared with time just leaving the orange tag line words it would be a clever way of getting people attention.

If the letters were on a poster on the underground you could make them lightly stuck on so every time a train went past more letters would fall of. Although there my be problems with littering and such.

Another idea is to have the poster out side so the rain or sun would make the grey letters disappear over time.
