Remember the lickable wallpaper from Willy Wonka and the Chocolate Factory? Well, meet the 'Sound Poster', which is pretty similar, except instead of licking it, you use your hands to touch it and make sound! (Okay, and it's a poster instead of wallpaper, but close enough, right?)

Graphic art design company Trapped in Suburbia have created this interactive piece of art, and you can see a video of it being used below. According to their website: "Simply move your hand over the different shapes to create different sounds. It is a first in a series of self-initiated experiments where we explore the boundaries of design where analogue meets digital".

If this is the first piece in this series, we can't wait to see what else they come up with.
