the shining tile by alessandra pasetti from italy

This tile has a painted decoration with phosphorus pigment. This allow the tiles to catch the sunlight and to glow during the night. It is just a simple white tile during the day but at night it reveals the decoration and some light!
It could be nice also to write in the tile messages you want to read in the darkness, such as “sweet dreams” or just an arrow that point to the light switch.
