playful art and architecture

After researching about Naef toys, their mission, and previous designs, I came across this blog that provides some examples of playful architecture in society. This type of architecture, practical or not, basically keeps the same sort of ideals in mind. It promotes imagination, creativity and an inspiring environment. Then I stumbled across this website for PLAY ART which has a lot of similar intentions as Naef. They want to provide society with revolutionary toys that interact the user in a much more design focused way.
