Graffiti by Banksy, Image via Holy Taco

As many of Banksy's works show, graffiti can convey social commentary. For example, the painting above, which shows a city worker sandblasting the famous Lascaux cave paintings just as he would modern day graffiti, wittily laments the blindness of local governments to public art.

A year ago today, the city of Boston was brought to a standstill by led advertisements for the Aqua Teen Hunger Force movie. Here’s how I described the incident way-back-when in viz.’s first blog post:

on Jan. 31, 2007, some members of the the Boston police force interpreted some electronic, guerrilla marketing devices for the movie Aqua Teen Hunger Force Colon Movie Film for Theaters as bombs. The city closed down bridges and shut down the river to boat traffic. In the ensuing fallout, video artists Peter Berdovsky and Sean Stevens were arrested and the president of Adult Swim resigned over the incident.

Today, graffiti artists and other pranksters have commemorated the incident by posting similar LED art all over Beantown:

I've always thought that the best graffiti is on train cars. Maybe it's not always the best graphically, but I like the statement--not only has the tagger tagged, but the canvas is mobile and likely to get pulled all over the country, set forth into the world. It's bold. Not as bold as the graffiti on interstate signs where some kid crawled out on a metal pole over 80 mile-an-hour traffic, but bold nonetheless.
