walltattoo

just saw this over at apartment therapy and i'm loving it. a design team in vienna created these gorgeous wall applications to add color and design to walls in need of a little help. from what i can tell, they're painted on- most likely by using a projected image on a wall- seems like a very one of a kind thing. availability is confusing, so i'm checking on it. just wanted to post it before i forgot. so pretty.

i'm wondering how easy it would be to design something similar and project it on our own walls? i'd love something like this in my own home, but i'm not much of an illustrator myself. what do you guys think- easy to diy or not worth taking on? all i can think of is trying to get a design onto transparency or film to put up there- costly? cheap?
