Scratch me by stefano merlo from italy

Scratch-me!
A transparent plexiglas panel, lighted from top and from the base by bright led lights, to be applied on buildings' facade or standing on squares.
The illuminated plexiglas board will glow if scratched, becoming in this way a sort of scratched guest-book, where people can leave their message simply scratching the panel.
In this way the building's facade will continuously change.
