Apparently this street art installation has been in place in New Haven since 2010, but I just noticed it last week for the first time. The artist is Felice Varini and this is his first installation in the US. While it looks like someone just overlaid a geometric design onto this photograph of this alley, this is actually painted on the walls of the alley and the parking garage behind it.
