Mitsuo Takeuchi's sculpture stands in the foreground. To the left is May Barrie's Angaston White Monolith 1987, to the right Kaoru Matsumoto's Cycle 90 Degrees "A Premonition of Wind III". Both of those have their own shots elsewhere in the gallery.

Directly behind and obscured is Jean Pierre Rives' untitled work, which doesn't currently have a shot of its own.

Addendum: My personal opinion is that Facebook is a sociopathic organisation that steals other peoples' intellectual property (including the images in this gallery) despite being explicitly denied permission to do so.
