I've been very interested in doing mosaics lately and I decided to try something a little bit more arty. I took a photograph of dylan, pixalated it using a graphics program, reduced the colors and screwed around with it a bit and printed it out. Then I tried to match various colors of commercially available vitreous glass tile to the colors in my picture, gridded out a piece of MDF and glued the tile on. A fair amount of trial and error was involved, but I'm quite pleased with the final, grouted product.
The first photo is a little blurry, which enhances the optical illusion, and second is from across the room.
The last is from pretty close and clear.
I've been experimenting with this technique on other sorts of images and have gotten some interesting results.
Here is a very close up picture that shows the details of the tiles. I really like that up close it has a crafty, home made feel, when from far away it has a somewhat photo realistic effect.
