Can an online crowd create a poem, a novel, or a painting?

Something similar like:

Tikatok™ is where kids channel their imagination into stories – and publish those stories into
books for you to share and treasure with friends and family.

, but for adults who have made storybook to read.

Even more explains this story what I'm looking for: Art Mobs by By Clive Thompson. I plan to make birthday present for my friend and trying to find storybook which has been written by online crowd.
I searched in Google, but got tired after more than hour long searching. Decided to come and seek help from Writers Corner maybe someone knows where to look or suggest something.

I knew a few sites, but I carelessly forgot them over time. I'll send word to some of my contacts. Maybe they'll help you out.
