Those blue, and white squares, look a lot like crochet granny squares.
Hmm, so they do. Anyone for a challenge?
Ooh, so many wonderful sights! I love the little line-drawn figure... such a cute guy. Also, your sunburst-castle-wall photo is fantastic! A little "plumping up" in Lightroom would make it even better... ;D I like the mosaic sidewalks, too.
That mosaic-y walkway is really neat!
