thanks for alerting me, I checked your post with a great pleasure!
already took part in week 3 of the contest, and hope to find something in the next week, as well.

PS> photos 1-2 are incredible, fantastic! tho it do not look like a 'graffiti' for me, at all :))) - looking at it, I cannot but suspect it is not for real, but Photoshopped. simply amazing!
