Archilogic, an online architecture viewer/editor designed to be easier for laypersons to use and share from than Sketchup, is spectacular stuff… at least on a fast computer. You can upload plans and convert them to 3D, move and replace furniture, mess around with the layout, push the results to friends or real estate agents, and so on. Some of the demos posted to the company's blog are fascinating: exploring Don Draper's apartment in the first-person is eerily voyeuristic. An unbuilt Frank Lloyd Wright design is more majestic and less, well, sleazy.
