The Prince rolling up a katamari of items in the "Katamari Damacy" video game may look like an exercise in consumer greed, but thanks to Jason Leivian from the Portland, Ore. comic shop Floating World, more than 40 artists have come together to be charitable by donating their Katamari-themed artwork to benefit a non-profit organization called JOIN that helps the homeless transition off the street and into a home.

The Katamari-themed artwork of creators including Jim Rugg, Jeffrey Brown, Douglas Sherwood and Michael Deforge is currently on sale via eBay, after display at a Floating World art show that earned the ultimate Katamari honor: a visit from Keita Takahashi, the "Katamari Damacy" creator himself, who added his own sketch of Noby Noby Boy to the art of Douglas Sherwood.

Check out all the Katamari art below, and go place a bid on your favorite piece to take it home -- and benefit a good cause that helps other people find homes of their own.
