Isaac Mazer (Ricecracker.) made this beautiful rendition of the cover of the Pink Floyd Album Dark Side of the Moon.
Here is the original for a comparison:
I love how Isaac used white, trans-clear, and trans-black pieces to achieve gradations of color. Using black can help to cover up imperfections in a cheese slope mosaic. If you look closely at the largest sizes of the photo, you will see that there is even a modified plate with a door rail with the rail part filling up a small area. In another color this might be more obvious, but with black it all blends together and looks great.
Thanks to Simon for the tip!
