Last year, a few Seattle nerds had the brilliant idea to launch a convention celebrating women in geek culture. The result was a sold-out smashing success, and this year, they’re gunning for a repeat. The two-day lineup includes everything from roundtable discussions on the female characters in Star Wars and the gender dynamics of Doctor Who to Buffy sing-alongs, steampunk sewing classes, and presentations on how to combat misogyny online. Basically, this con packs everything nearest and dearest to your geeky feminist heart into one empowering weekend. (Washington State Convention Center, 800 Convention Pl, www.geekgirlcon.com, 9 am–6 pm, $30, through Aug 12)
