When I work from home I have a ritual of walking down to the local coffee shop, buying a coffee and then walking back before starting work, it's kinda like seperating work from home, I leave home, lock up and start my journey to work, on the way I buy a coffee, and then I head to work, which just so happens to be home.

This morning on the way to work, I discovered this site. Luckily I had my phone with me.
Is it art? Is it a practical joke? Knowing Brunswick Street either is possible. I'm just curios how long it's going to last there.
