A City of Toronto anti-littering campaign doesn't sound like it'd generate much interest (just more finger-waving from the town that hates fun), but occasionally clever creative work can overcome even the most boring of subjects. Such is the case withLive Green Toronto'snew anti-litter ads, which are designed to shame garbage tossers by reminding them that "littering says a lot about you."

It's the most simple of devices, but the message spelled out by combining bits of trash is actually rather memorable. When recentlyposted to Tumblr, for instance, the set of adds racked up over 130,000 notes in less than 24 hours. Oh, and they also allow the the city to call its littering residents and/or visitors "pigs" without being overly insulting. Here's a look at the ad campaign everyone's talking about.
