MAD's Urban Forest skyscraper is simply that: mad~

You may remember MAD Architects from their equally mad designs, such as this star-shaped floating city. Now they've got the wobbly-looking, 1,250-foot-high Urban Forest for Chongqing, China that does away with the traditional walled skyscraper for one that's a series of terraces~

From MAD:

...The Urban Forest no longer emphasizes on vertical force, instead it concentrates on the multidimensional relationships within complex anthropomorphic spaces: multilayer sky gardens, floating patios and minimal and yet well lit nesting spaces, the architectural form dissolves into the fluid spatial movements between air, wind, and light. In this environment, people encounter nature filled with unexpected surprises~
