What function will it fill? Something tells me this type of building is primarily promoted by utopic socialists. (see venus project) But if there's a function to it, then that's great.
Also, of course experiments are welcome. Just not with money that was "taxed" away from me, without me having a say in it.
The designers behind the project say that the purpose for this building was to show other developers that prestigious buildings can be made without bending the law (Which a lot of developers seem to do to build taller buildings). Another purpose is to use more space in an efficient manner.
