I just cut a piece of plexiglass to fit the housing of clock 3. The back is sprayed with black paint, just enough to simulate the smoky effect but transparant enough for the red light to come through. I have to sort out the electronic part before I can fix the top of the housing to the rest. And still to do: buttons and a red led to show the alarm is on on the left of the front. The housing has already 2 holes for the switches that will double as feet allowing you to smack the clock to silence it.
