If you thought it was strange that Kanye West released his album artwork in the form of a clear blank CD case with a piece of red tape carrying the album name, there is actually a plan to his madness. After confirming the photo on Twitter for his forthcoming album, Yeezus, he also added the text: "Please Add Graffiti".

What does this mean? It seems fans can join in on the artistic direction of the album's design by creating their own.

Are you up for the challenge?
