I always seem to change my mind about wall vinyl stickers. The trend has been a bit overblown and has always seemed a bit cheesy to me, but then something always comes along which tries to make me change my mind. At the moment, I quite like the wall vinyl stickers by Adrien Gardere. Especially the Arco Shadow (larger photo here).

It’s a lot cheaper then buying a real Achille Castiglioni Arco Lamp, and it’ll save you space. Probably won’t improve your lighting though.

If you like wall vinyl, check out the great range available at POAA.
