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
In Rear Window, Jimmy Stewart plays a free bird, an adventurous action photographer named L.B. Jeffries whos scared to death of being caged in marriage even if hed be sharing the friendly confines with the gorgeous and lusty Grace Kelly. The first joke on Jeff, at the very beginning of Alfred Hitchcocks impeccably framed 1954 film, is that hes immobilized by a broken leg and confined to his New York apartment, dependent on his high-toned darlings occasional visits for stimulation. When our emasculated hero thinks he sees some bad behavior across the courtyard, he can rely only on his enormous telephoto lens one of the more inspired phallic symbols in movie history and his feisty, thrill-seeking girlfriend to penetrate the mystery. The folks at Film Night in the Park astutely set this outdoor screening in the heart of downtown, surrounded by rising walls of brick and concrete and hundreds and hundreds of windows. For Rear Window is not only about sexual role reversal, but voyeurism. Raymond Burr is wonderful as the bulky, hulking suspect who challenges our sordid desire to peer into other peoples lives, an urge that has been exacerbated, and as yet unsatisfied, by reality shows, amateur videos, and Webcams.
