Have you always wanted to embody the feeling of freedom of walking at high altitude? Then go to the HangarBicocca gallery in Milan. The designer has built an interesting aerial walking facility here. There are three strong transparent plastic covers spaced several meters above and below each other. You can run around on one of the floors. Jumping around, you must find it very enjoyable. The real purpose of this facility is not to let you play happily, but to make you realize the time or space relationship between people through the deformation of space.
