Here's a pic of Anaglypia used on the wall behind a vanity. It was glazed and painted to represent an aged copper ceiling. Pretty cool. I thought I had a pic of a ceiling done too. One thing for ceilings is that you should use some sort of crown moulding for the edges - like an old tin ceiling would've had to finish it off right. I've seen them done with the faux tin finish - aged and then copper aged - and they look great. I would practice the finish technique on scrap before I tackled a whole area tho!!
As for where this can be used - a bathroom is a great location - especially a powder room that doesn't get a ton of wear and steam. A hallway as a wainscotting works well; a library; a dining room ceiling; a foyer ceiling/wainscot etc. It is compressed paper which is molded into these patterns, then you can finish it your way - it can be repainted again later if you change your decor or it needs refreshing. Lincrusta is great - I have it in my bathroom - had a pro hang it tho because it is tricky and I'm chicken - but I love love love it. Either of these things were popular thru the 1920's and there's appropriate patterns to fit different styles. A good paper store will have it or you can find it on line. Fun!
