It's the end of SFMOMA as we know it, but the museum isn't going dark without first unleashing a four-day celebration of general revelry. Starting today at 10 a.m. and ending Sunday evening with a bittersweet farewell processional, the museum will host a series of free events (and will be correspondingly packed to the gills).

All day today and Friday, award-winning radio producers The Kitchen Sisters and KQED will be on hand for The Making Of, is a multimedia series about what people make in the Bay Area and why. They'll be exploring everything from camping, kimchi, surfboards and stories with demonstrations and discussions to entertain and enlighten, culminating in two movie screenings at the Roxie Friday night.

Things kick into high gear tonight, with the Countdown Celebration Kickoff party, a museumwide fete featuring a sangria bar by Coqueta as well as bites, beer, music and a t-shirt screen-printing station.

The weekend presents your last chance to check out the 24-hour installation of Christian Marclay's The Clock, with the final screening coinciding with the very last minutes before the museum's closing on Sunday evening.

Our personal pick from the museum's lineup? Sunday afternoon's creative activity, wherein museum guests will get to make their own tin foil time-travel hats with Oakland-based milliner Teri Sage. "Wear it and participate in the procession to the future!"

Of course, this 'see you later' rather than 'goodbye'. The museum will be back and better than ever come 2016, bigger by 225,000 square feet and sporting new vertical gardens, as well as other improvements that only $600 million can buy.

We leave you with this video, shot by Caitlin Donohue, of Supervisor Jane Kim and retinue of adorable kids counting down to a glitter bomb at yesterday's groundbreaking ceremony for the new and improved SFMOMA.
