Urban street art right up my alley

I like art that is clever.  On a recent trip to Powell's Books, I was highly amused by the miniature art in Slinkachu's book Little People in the City.  Slinkachu takes little figurines and creates scenes in the urban enviroment that are humorous and thought-provoking. 

His tiny installations have been in a number of European cities including London, Amsterdam, and Barcelona.  After photographing the models, Slinkachu leaves the installations on the streets for others to discover.

Slinkachu's urban art reminds me of another artist's work.  German artist Jan Vormann fills small gaps in walls with Legos, one of my favorite toys.  His work was spotted in New York City just a few months ago.  Other cities he has "repaired" include Tel Aviv,  St. Petersburg, and Quito.  A visual documentation of his Lego constructions can be found here.
