We have a rogue basil plant growing in our front yard - it is sprawled over part of the sidewalk and is pretty unsightly, but it does have these pretty little clusters of pink/ lavender flowers all over it!

I used picnik.com and used the cross-processing effect and a vignette.  This is the sort of cross-processing I would LIKE to do in photoshop - more green than blue.  I am getting there :).
