The Amazon Mechanical Turk (MTurk) is ... a crowdsourcing marketplace that enables computer programs to co-ordinate the use of human intelligence to perform tasks which computers are unable to do. Requesters, the human beings that write these programs, are able to pose tasks known as HITs (Human Intelligence Tasks), such as choosing the best among several photographs of a storefront, writing product descriptions, or identifying performers on music CDs. Workers ... can then browse among existing tasks and complete them for a monetary payment set by the Requester.via wikipedia

Crowded is an as-yet unreleased radio show/podcast that is made up of segments of audio recorded by Mechanical Turk workers. Each episode has a mechanism, such as:

We are creating several different designs for suspended, hydroponic, modular, low-energy, high-yield light-augmented window farms using low-impact or recycled local materials. These prototype window farms, to be located in high-profile windows throughout the city, are intended to inspire other New Yorkers to design and implement their own window farms. Signs in the windowfarms will challenge New Yorker to create their own and direct them to a website where we can all share photos, plans, designs, and information. Together, we will derive viable methods for growing food under the local conditions of our own homes in a way that is efficient enough for New Yorkers' lives.
