What is "twentywonder"

TwentyWonder is an annual, one-night summer festival held in the Los Angeles neighborhood of Echo Park. Since 2011, TwentyWonder events have been hosted by the Los Angeles Derby Dolls at their venue, "The Doll Factory". Event lineups consist of several dozen local, alternative cultural attractions. Those attractions typically include women's roller derby, national and international music acts, science exhibits, makers, magicians, comedians, and circus performers.
