192 squares in size 2" x 2" ( 51 x 51mm ) - that's all !
...and in the dark room this light casts colorful shadows on the wall.
I found the perfect glass to go with this very transparent design at Spectrum Glass with their Water Glass series.
These glasses are slightly wavy on the surface - so, as seen in the detail photo on the right, actually straight lines lying in the background are slightly blurred - a real highlight !
