Garbage + illumination = art? Various artists carefully pile rubbish on a gallery floor, or meticulously assemble a collection of ordinary items, plug in a light source, and create incredibly detailed and surprising shadows on the wall. Meanwhile, blog commenters cry "Fake!" and "Photoshop!". I guess they didn't see any of the Quicktime movies of Shigeo Fukuda linked here.
You've probably seen those photo mosaics where a large image is made up of many smaller images acting as pixels. Kelly Houle has taken the idea a mile further by creating a photo collage that is also anamorphic -- a collage of illustrations and related material from Alice in Wonderland that, when a curved mirror is placed in the correct position, forms a portrait of Lewis Carroll. Absolutely amazing stuff.
