You might think six columns is too crowded but Greenline and Dexigner work pretty well on even a 19 inch screen – maybe it's to do with having six stories to choose from on the screen all at once - and sometimes more.
Each story has an image, heading and explanatory standfirst (as they are called in the trade) and you click for full details and more images.
Greenline's six categories are News, Architecture, Products, Case Studies, Energy and Environment. The individual articles are actually quite gripping – for example: how the Bejing Olympics National Aquatic Centre facades are based on the possibly little-known Kelvin's Conjecture; how Greg Lynn's Blobwall is less modular than individually handcrafted; a countertop made from recycled counterfeit money; a building performance simulation plug-in for Sketchup and other terrific goodies.
The only down side is that at the moment they don't run a RSS or email feed. But in its early days it's small enough to download the whole thing and browse at your leisure.
