Labyrinthine

 Crazy complex detail work by Motoi Yamamoto.
These installations are made entirely out of loose salt.

Another Plastic Brick In the Wall.

These are by one of a collective of 21 artists that did site specific work in a little European town. (Italy?)

No name was given for whichever individual did these in particular, and it might have been several. Still it's just amazing simple little pieces that just work so well. I always apreciate thoughtful yet unobtrusive public art, it's the sort of thing that makes the world a better place to live in.

Of course some people have a differen't opinion of what is considered unobtrusive than I.
