Run linear fish tanks embedded along the entire length of the walls of underground train stations.
Instead of peering up gloomy tunnels waiting for trains, commuters could contemplate the calming movements of the fish world as they lazily swim up and down the platforms.-- xenzag, Sep 02 2009 Reminds me of the fish tank bathtub idea. + (oh yeah, another + for the title.)-- blissmiss, Sep 02 2009 Train these creatures to follow a crack commando unit (one that might have been sent to prison by a military court for a crime they didn't commit - before promtly escaping a maximum security stockade to the Los Angeles Underground, still wanted by the government, they survive as soldiers of fortune) and you have Fish That Track the "A" Team.-- zen_tom, Sep 03 2009 so the underground is not solely for werewolves anymore, but great white sharks might roam there too? Movie producers will shower you with money.-- loonquawl, Sep 03 2009 I was thinking more along the lines of common tropical fish, but each station could have a theme. Naturally the predators would gaze out hungrily at the suited bankers waiting at Wall Street.-- xenzag, Sep 03 2009 It would be interesting to catch lawyers and investors in their natural habitat, but I think you'd have to clean the tank often. They tend to suck onto the bottom of the tank like other bottom-feeders and block the view.-- RayfordSteele, Sep 03 2009 "Chased by a Randy Dolphin Commute" ?
