Museum folk get to witness some of the most bizarre things when the museums are closed. Case in point: On SFMOMA's blog they have been documenting the "deinstallation" of the notorious Sol LeWitt works that have been occupying the lobby there for the last eight years. Friday they posted a wonderful video of the process. Check out the video here.
[Just a side note: The LeWitt peices are being deinstalled to make room for the Martin Puryear exhibition that was here in the spring]
