Building blocks

Is the name of this piece, part of the "Tunnel Vision" installation in the Bethesda metro station tunnel in Maryland. It could be called "Corporation Alphabet" because if you look closely, you'll recognize cut outs of famous brands displayed as alphabet blocks.

I really like coming across those public art projects in some unusual places, meaning not a traditional art gallery. They not only showcase local artists, they bring art to people who might not visit art galleries or museums.
