Boston's MBTA (aka the T, or "subway"/"metro"/ "L" to outsiders) has announced that they will be unveiling super duper high tech electronic billboards with the ability to wrap images around columns. (Garelick Farms is first at bat for this new technology). AdFreak aptly points out that after the Aqua Teen Hungerforce scare, Boston might not be ready for something like this.
Interestingly, the MBTA went in this direction a few years ago. I was riding the red line out to Harvard Square and all of a sudden bright flashes appeared on the tunnel walls. Once I realized I wasn't having a freaking SEIZURE I focused in and saw ads being displayed in rapid motion on the tunnel as we flew through it. I'm not sure if those ads are still in the red line tunnels, but with these new ones in the mix MBTA stations might start looking less like filthy crap holes, and more like the mall from the Minority Report. Up next - T-pass chips embedded in your eyes! Or something... ya.
