Merging urban exploration with something akin to La Blogotheque's Take Away Shows, the below video gives a glimpse at what's hidden in the Atlantic Avenue Tunnel underneath Downtown Brooklyn while performer Greg "Cosmo D" Heffernan scores the journey.

The video is part of an online magazine called NY Moon. Each month there are several features including one called "Blueprint" which proposes new ideas for NYC. In February's issue someone suggests New York's billionaires buy up advertising space on the subways to allow for art and other projects; "One station in Queens might allow Swoon and other so-called street artists curate. Another might choose to paint a blue waterline where the floods from melted icecaps might reach." [via NY Press]
