Translucent cement

I want to build a small cabin out of LiTraCon on the Kuhlman farm, with a similarly translucent fiberglass roof. Moonlit silhouettes of the forest canopy would perhaps help recreate a tent-like atmosphere in a more permanent structure.

Another fun use would be illuminated paving. Especially if the illumination is provided by addressable panels. Blinkenlights for plazas!
