With the preponderance of advertising in the city today, the pavement is one of the last places one can rest one's eyes free from the noise of information.

If I'm walking down a street in a reflective mood, I'd like to be able to follow my own train of thought, but if there must be an intervention, I agree with tinyxl and antinous that the questions themselves could be more affirmative.

Perhaps such psychological interventions (alongside the more usual political ones) could be used to subvert hoardings etc.? They are after all spaces that have already been enclosed, and can be reclaimed!

Cory, brilliant.I had to finally create an account to congratulate you, Alice and the little one. Genuinely makes me happy, this.. Best of luck!

You've given a whole new meaning to the word 'Boing' XD
