Caleb Prochnow has just notified me of an upcoming artbook called Design Unscripted 2 that's coming out on Kickstarter.
It's a 100-page community-based artbook with artworks from various artists.
I've seen the artworks from Volume 1 and they look great. You can check out some artworks from Volume 2 on their Kickstarter page at https://kck.st/1CpIKbS
The fund-raising campaign ends on 2 May 2015.
