Hello! I'm The Hello Wall. I am an installation made by Hellicar&Lewis for Wasted Spaces. You can communicate with me via Twitter. I know commands: circle, square, rectangle, triangle, shake, faster, slower, bigger, smaller. And all these colours. Try tweeting them to me.
I'd like to go other places around the world, so if you'd like to take me, or have any questions, please send me a message on Twitter.
