But thanks to a visit last month to Kanazawa's 21st Century Museum of Contemporary Art (which happened to be devoting several of its rooms to displaying works by Leandro Erlich) , I actually have a photo that can be used to combine both these themes!
Firstly though, here's presenting the kind of photo I'm more inclined to take on my travels: i.e., of Puppet Ponyo -- as opposed to myself -- in the aqua (or it is azure? ;b) colored underground room that's part of Leandro Erlich's famous Swimming Pool installation. And next up is a view of the artist's Invisible Garden in which those peeking into it don't have their images reflected in the windows or are visible through it.
While that may not strike people as unusual, consider this: that from certain angles, one's reflection does become visible -- thus enabling people, like yours truly, to take a selfie from a distance! Also, thanks to the clever placements of mirrors and such, sometimes the plants inside the garden at the center of the room -- and is an installation that does take up a whole large room on its own -- look the same throughout while from other angles, one can see two different sets of floral arrangements within it!! ;b
