Example of Crowdsourcing

There are many examples of Crowd sourcing to find over the web, however I found 2 interesting cases of crowd sourcing these are;

James Patterson's Airborne: 

James Patterson is a best selling author, however he created a book named "Air Borne" however he only wrote the first and last chapters and then let the public complete the other 28 chapters. This is an example of collaborative crowd sourcing because its a task that normally a employee would carry out although it has now been a set task for the public.

Thread-less - Twitter Tee's:

Threadless.com allowed for people/public to nominate their favorite twitter "tweets" and then have them turned into t-shirts, this could of resulted in a $500 reward for the creator of the tee's. This is an example of crowd sourcing as it involved the public creating a tshit to be sold making this a collobrative effort of people.
