Abduzeedo

Creative and interesting visual/graphic art, plus some useful tips - Started by a Brazilian graphic/web designer, Fabio Sasso, Abduzeedo is a blog about the design world, its elements, and art experiments he's captured thus far. A fun site to peruse and get useful information from (it has a tutorials section, most of which is focused on techniques in Photoshop).
A number of the collections he highlights are of every day people, places, and things. For example, Anderson Augusto and Leonardo Delafuente paint urban objects (e.g. Storm drains, light posts, etc.) throughout Sao Paolo, the goal of which is to modify the way people view and reflect upon art, transforming daily life in their neighborhood by focusing on forgotten and/or indifferent objects: http://abduzeedo.com/amazing-gutter-art
Also good is their piece on High Dynamic Range Imaging (HDRI) pictures: http://abduzeedo.com/20-beautiful-hdr-pictures, with an accompanying tutorial on how to create them, and 3D chalk art by Julian Beever and Kurt Wenner: http://abduzeedo.com/amazing-3d-chalk-art
