I came across this on the Aus_NZartquilters list and had to share.
What I love most is how they are created.
Basically (although there's nothing basic about it really) he prepares a series of panels that other artists then paint. The artists don't know what the final image is so they are not influenced by it.
It's quite ingenious really - by giving the artists a base, and some loose guidelines (colour, tone or shape) Lewis is able to reassemble the artworks to make the originally planned image.
Perhaps this is how I could look at making my mosiac (without the element of surprise of course). Choose and image, blow it up, cut it up, create individual artworks and then reassemble them.
