I think that this image could symbolize a part of Romeo and Juliet. It's kind of abstract, but the slightly raised walls on either side of the heart remind me of each house, Capulet and Montague. The heart is representative of Romeo and Juliet's love, which has managed to cross the "barriers" set by their families' feud.
I got the picture from a stock photography site. I'm not precisely sure who to credit, but this is its page in the gallery: http://www.sxc.hu/photo/1083039
