Classical Mosaic
This one is a free form mosaic from a few year's back, using venetian glass and rocks. This is a seriously filthy form of art, I recommend having a shed or garage to work in if possible, it makes a serious mess! It's a wonderful form of art tho, like a combination of lego, jigsaw puzzle and painting, you can do so much with it, but you do need some space, it takes up a lot of room.
