Old-school bOING bOING pal Jim Leftwich says:
The Sun Hive is a hanging honeybee hive designed by Günther Mancke and which is growing in popularity in the UK and elsewhere. It was designed around the needs of pollinating bees and colony health and preferences, and not around prioritizing honey production. As such, it's thought to be much better for sustaining bee populations. It's also quite beautiful.
There's also a Sun Hive book, that you can read or download (4.5Mb), and which gives the background on natural beekeeping and instructions on how to construct one.
