'Change It' is a wall of analogue triangles that turn, each triangle has a white, black and a shade of rainbow colour on it - simple really, but visually effective. Like a big mosaic puzzle for adults that can create a myriad of playful designs according to mood or the function of the room. Moving forward, it could definitely be digital and become limitless with the combination of possibilities, with each square representing a pixel or multiple of pixels - but I still like this analogue version.
Here's another article about the 'Change It' wall with a load of comments which are an interesting read - some people are getting really angry about how it would/wouldn't work. Personally the simplicity of it is what I like, it doesn't become intimidating - just playful - and the authors of some of those comments should just relax more!
