Street artist Slinkachu released four new tiny sculptures into the city to mark the launch of his new book this week and five intrepid hunters from the Londonist team set out to find them in a specially designed treasure hunt. In an afternoon's muggy and damp tramping around, we went from the COSH gallery where Slinkachu's work is on display into the West End, to South Bank and right the way over to Brick Lane.......

As an antidote to last week's focus on BIG graffiti, here's proof that size isn't everything. The Inner City Snail site chronicles a 'slow moving street art project', and comes from the same tiny stable as the much-loved Little People web site. Creative genius Slinkachu assures us that 'No snails were harmed, they just had their homes vandalised'. Catch the book of the site later this year.......
