MOCpages user, alyska bailey peterson, creates an absolutely beautiful stained glass window.
Here's a description of the mosaic MOC via the post on MOCpages:
This trans Lego stained glass mosaic, measuring 15x28", is based on the stained glass window "Creation: Day Four" at the Church of the Sacred Heart in Bilton, Rugby, England. The original window was designed by artist Aidan McRae Thomson in 1998-9.
This is the first in a series of five panels based on the creation story that I'm working on, hopefully to exhibit as a pentych at Brickworld 2011 in Wheeling, Illinois. (I'm already halfway through the second panel as of this posting!)
