This is a call to art for anyone who hasn’t yet checked out “Take Your Time: Olafur Eliasson,” on view now at New York’s MoMA. Um, check it out now! [Said in gruff art-snobbery voice.] In addition to the exhibition, fans of Eliasson’s insane experimental art should pick up the latest Taschen art release, Studio Olafur Eliasson. An Encyclopedia (528 pages, $150). Up next for the Danish artist is the creation of four man-made waterfalls in New York Harbor. The installation is set for a fall unveiling later this year.
