Why just tile when you can be artistic
When the guy at the tiling shop said I could break up the grey tiles by running a strip of blue glass tiles though the middle, he did not allow for my imagination. I decided it should be a stylized waterfall from a mosaic lake. For $20 I picked up a box of assorted glass tiles from Reverse Garbage. Sorted them out on Saturday night and here I go. By the way the waterfall becomes a river on the floor that meanders across (not shown).
