i got to play with the real-life version of this Calder at Centre Pompidou in Paris. i literally spent a whole afternoon blowing with my breath or fanning it with a newspaper til i got it to move all its parts.
it is still one of my most favorite memories of my last visit to France.
ALSO! now you need to find a bigass Miró poster and put it in that wall behind it. the show cleverly also had a mini-Miró show so people could compare and contrast.
