That's nice Ulco
Ok let me explain you the idea.
I just bought a house few weeks ago. Number of the house is eight.
I had the idea to replace the basic frontdoor number (as example here)
by a 40 x 20 cms terragen landscape including the number.
First idea is a seascape as I did for my bookmarks with a 8 floating on the sea.
It should be original even if a lot of houses have some ceramics like second picture.
