That's Steven Holl's Museum of Contemporary Art (aka Kiasma) in Helsinki, Finland.

Thanks archidose!

is that the one thats closed?

No, the Holl museum that closed is the Bellevue Art Museum in Washington State, though it's supposed to reopen late October (details here).

i love the crazy effects of scale in that project...really disorientating. hope it does open again, would love to see it in person.

why did it close,,, east coast here so not in the loop

The usual, lack of funds.
This article briefly touches on its closing last year.
