i was just about to post about wall decals.
there are so many companies that make these now a days, not just blik, all you need is to google what you are looking for. Blik, wall pringt and stickyups all make the bamboo shape you are looking for.
Currently apartment therapy is having a giveaway contest you might want to enter (the BLICK bamboo decals are one of hte prizes).
(edited to clarify the last sentence)
