I made this mosaic in 5 individual sections to make it easier to ship it to its destinatin, much like my other dice mosaic.

Opposing faces on a die always add up to 7. A surprising side-effect is a negative image that forms on the reverse side. Here, I flip one of the tablets to reveal it.

While I take every care to avoid adhesive sipping through to the face of the mosaic, I don't give much thought to how the back looks.

I am pointing out how dirty the back of my mosaic is for the camera. All this talk of "tablets"... Reminds me of another type of image :=)

After final assembly on site, I drive two machine screws into the mosaic's back and wind a string around them. Even without a frame, the complete piece has some thickness to it. It is strong enough to carry its own weight with no backing or frame of any kind.
