Mosaics don't always have to be big and complicated to make a nice image. Bruce sent me a link to this one, made by Brickshelf user lego036, saying it was simple, but that he liked it.
I really like it too. Upon closer inspection, I can see that the eye is made of a round brick, and I'm fairly sure that the beak is made with a headlight brick. The stud on the side of the headlight brick sticks out a bit, to give the beak a slightly pointy look. Very nice.
lego036 had a few other similar mosaics, too. I love how the bird is holding a leaf in this one:
And it's very easy to imagine these cute little fishies swimming around in a koi pond:
As an aside, I find it very limiting that I can't leave comments or really contact in any way the Brickshelf users that are featured here. For that reason I usually stick to flickr and MOCpages as sources for blogging. I'll try to make more of an effort to check out Brickshelf, though, in the future.
