When the ancient Polynesians invented surfing, they often used a paddle to help them navigate. Fast-forward a few millennia, and Stand-Up Paddleboarding, or SUP, finds itself trendy again. Part of its increasing popularity is that standing upright allows surfers to spot waves more easily and thus catch more of them, multiplying the fun factor. Paddling back to the wave becomes less of a strain as well. The ability to cruise along on flat inland water, surveying the sights, is another advantage. Finally, its a good core workout. If youre sold on the idea, schedule an intro SUP lesson, free with board and paddle rental, and you may find yourself riding the waves like a Polynesian king.More
In the past 30 years, light artists have reimagined an art form that has always had the ability to turn the night sky, or a simple window, into luminescence. Last fall, the Yerba Buena Center for the Arts turned its southern glass wall into a parade of sound-sensing lights, Lightswarm, that changes with the movements of nearby people and things. Future Cities Lab, the San Francisco design company behind Lightswarm, has originated another notable light sculpture. Located by the YBCA's steps at 701 Mission, Murmur Wall will light up in arresting ways as it incorporates local trending search engine results and social media postings. Onlookers can offer their own contributions, which will feed into the Murmur Wall's data stream and light up the sculpture. What's trending in San Francisco? If you're walking by the YBCA, you can see firsthand — at least through light patterns that reflect the city's volatile internet habits.
Murmur Wall debuts Thursday at 6 p.m. and continues through May 31, 2017, at Yerba Buena Center for the Arts, 701 Mission St., S.F. Free; 415-978-2700 or ybca.org. More
It can be dispiriting to be an art-house film programmer in the Internet age, since there's always the risk of some bore perusing your hard curatorial work and declaring, "Nice lineup. I assume I can get all of these on Netflix?" Joel Shepard, the film curator at YBCA, provides a witty answer to those creeps with "Screw Netflix: Movies Not Available on DVD." The series is now into its second month, and today's screening, Vernon Zimmerman'[s Unholy Rollers from 1972, has a host of things to recommend it: 1) It's a Roller Derby exploitation movie. 2) The star skater is played by the 1970 Playboy Playmate of the Year, Claudia Jennings, and she works at a cat-food cannery at the start of the film. 3) The other star skater is a lesbian. 4) The lesbian pins Jennings to a pool table and takes off her clothes. We'll leave you to discover the rest, but know this: You might have to shield your eyes from its brilliance. Also, this is weird, but Martin Scorsese was the supervising editor, and Unholy Rollers came out just a year before Mean Streets. Something's going on there.
