I quite like the Steiner classrooms I have seen, soft pastel walls, kids art and crafts on display. Not so keen on anything else but that is nice. They felt friendly and comfortable but not in your face.
I do agree though perhaps reading posters on the walls is more educational than counting the ceiling tiles.
I found that my early statistics education was greatly edified by determining the number of holes in an "average" 12" acoustical ceiling tile, actually.
Yeah, okay-- so taking my book away so that I'd pay attention.... probably not a terrifically successful tactic, all in all.
Interestingly, the library had a nice low-key decor, but I have no recollection of ceilings there.
