I don't know if street art ever really works indoors. If you domesticate an animal, it goes from being wild and free to sterile, fat and sleepy. So maybe the art should stay outside.
BanksyImagine a city where graffiti wasn't illegal, a city where everybody could draw whatever they liked. Where every street was awash with a million colours and little phrases. Where standing at a bus stop was never boring. A city that felt like a party where everyone was invited, not just the estate agents and barons of big business. Imagine a city like that and stop leaning against the wall - it's wet.
