Check out this beautiful tire art by Wim Delvoye.  I found it on Junkculture.  

Junkculture is a really interesting blog.
"Junkculture was launched in 2009 as a blog intent on bringing readers an eclectic mix of visual culture and curious artifacts from around the web."
Another cool thing I found while poking around Junkculture was some of my friend Kyle Hilton's Paper Dolls.  Kyle started making these amazing paper dolls recently, and they are taking the internet by storm!  I'm so excited for Kyle!  Make sure you check out his website, it's awesome.
