In homage to the brand’s roots and their first “Naked Ping Pong” parties, SPIN will also introduce casual play to entertainment concepts ideal for groups that include state-of-the-art old-fashioned Pong machines from Atari. Ballet Austin’s Butler Center for Dance & Fitness, who offers adult classes in a range of dance disciplines, will have one of their talented hip hop dance instructors to teach some basics so everyone can dance until closing time.  And keep an eye out for some very special party pumpers throughout the night.
