I first noticed it in a neighborhood of Boston aptly called the "Innovation District." On a crumbling corner of an old brick building, there was a gaping hole created by about 15 missing clay bricks, filled in with about 500 Lego blocks.
I was determined to find out who the artist was.
"I don't know!" I was told by folks working in the building. Their property manager had no clue, nor did the people at Lego.
