Art vs. concrete
Street art is not vandalism. I think this mindset is something the future will change. I hope. The streets should be a gallery, rich with colour and smart ideas. Yes, it disrupts the grey uniformity of concrete. Isn't that a good thing? The government should design street signs to be aesthetically pleasing, and telephone booths, and everything that creates the urban landscape. There should be stricter building regulations based on appearance. I'm sure everyone would be happier.
Banksy makes clever & cunning art in London, if you haven't heard of him, take a look at his website.
