I'm a bit of a sucker for bird feeders, weathering the clouds of doves while attempting to spot the occasional song bird or Monk parakeet. (I really hope bird droppings make good fertilizer, because the houseplants are about to be moved out on the deck directly underneath my feeder from TerraCycle.)
I also happen to be sweet on flat-pack products for even less of a good reason. I suppose they scratch the same itch as Ikea furniture and Chinese takeout boxes. It's neat to see what can be designed given the restriction, even if the one thing we have in amply supply in the States is shelf space.
So! Will I buy this "Architect's Birdfeeder," made of eight interlocking pieces of flat-pack acrylic? No, because I already have a bird feeder. (Two actually.) But it's only $25 and is oh so modern. You'll be attracting Scandinavian birds by the dussin.
