Was helping a couple of friends out for Noise Singapore Public Exhibition. We were given this two walls and we decorated it with many many SMILES!
Here is the idea, You can take any smiles you like from the walls, and make sure you return one with the post it note provided and paste it back at the place where you take the smile from! :)
It was really fun experience. and was glad to see so many return post it with interesting and some heart-warming messages~ :)
