‘Hoopin’ Happy Hour and Clothing Swap.’ Because what says a good time like hula hoops and swapping clothes? Longtime indie East Austin theater the Vortex widens its own playful, well, vortex with a regular Thursday happy hour. Bring your hula hoop and hoop it up in the Vortex’s shady yard. Bring the forgotten items from your closets and trade them out for new duds. Drink specials include $1.50 Lone Star and $2.50 Shiner Bock. And the theater’s café serves sandwiches, cheese plates and desserts. 5 to 7:30 p.m. every Thursday and Friday. Vortex Theater, 2307 Manor Road. Free. www.vortexrep.org.
