She has created these tiles by pushing clay into molds; the glazes are beautiful, though I haven't really captured them here. The groupings suggest topography and landscape (and cityscape, too, I think.) While numbered to ease recreation of the installation, I am intrigued by the thought that they could be manipulated by the viewer. It seems an interesting manifestation of the artist's intent and the viewer's perception. Also, it's always fun to build with blocks.
