I participated on a mosaic game. A picture, devided inti 18 pieces, each given out to a different artist. THe fun this is you have no idea where your part is, or how it connects to the next one, or what the total is. Mine is the brown one, on the rigth, near the bottom. Really fun to do.
Thanks to Laura S. Fiat who organized it, and Wes Douglas who provided the origical picture.
