A long time ago (actually every Sunday, noon-3pm) in a galaxy far, far away (in fact, Studio Gracia in SoMa) ... there came a troupe of heroes to teach and uphold a masterful tradition of movement, grace, control, and oneness with a universal force. No, not yoga — think Yoda, and picture Force with a capital F. Then envision a choreography class filled with lightsaber-wielding Jedi aspirants eager to keep the Star Wars legacy alive IRL. Not that there's any danger of that boundless franchise running out of nerd fuel, but the Golden Gate Knights, organized by Alain Bloch, certainly have a stellar thing going. Who wouldn't want to learn the "fancy flourishes and spins, including forward and reverse spins, inverted grips, and figure eights" of lightsaber brandishment in an atmosphere so respectful of its Jedi legacy that each class begins with five minutes of meditation? You get a little exercise out of it, too — in no time, it'll bye-bye Jabba, hello Leia.
