Graffiti has ditched its renegade roots and cleaned up its act—quite literally. A U.K. company called Street Advertising Services helps its clients catch attention with a process known as reverse graffiti. For a price, you can have your company's logo or advertisement power-washed onto dirty sidewalks, roads or walls. These super-clean areas show off your message to passersby and convincingly demonstrate that few spaces are safe from the reaches of guerilla marketing.

Annoying boss? Irritating coworkers? Up to your ears in reports? A new book, Working for the Man: Inspiring and Subversive Projects for Residents of Cubicle Land, gives you DIY ammo for navigating the dark underbelly of office life. You can learn how to organize a covert who-can-hold-their-breath-longer contest during a boring meeting or give yourself a mini-vacation by choosing from a list of inventive sick-day excuses. There's a good belly laugh in every chapter, but if your boss catches you carrying out these projects, brace yourself for the inevitable chewing-out.

Andy Warhol may have become famous for his soup cans, but two New York-based art directors had a more altruistic goal in mind when they painted a spiral ham. The pair sold their strictly decorative pork creation for $100, then donated every cent to a food bank. It's just one warm, fuzzy story from Needs For Sale—an online art project that lets you bank good karma as you decorate your walls. The concept is simple: You buy a painting of something someone needs—like a warm coat—and all the money goes to a relevant charity.
