Roll up your sleeves: it’s time to wash and wax the public sculpture of Austin! This Saturday, October 11 at 10 am a professional conservator will explain the proper maintenance of public art (with a video!) at the Austin Museum of Art’s community room, then lead wanna-be art janitors into the field for down-and-dirty practical experience. RSVP to Katherine Macy, (512) 974-9308 or firstname.lastname@example.org. After a day washing Austin’s sculptures, spend Saturday evening playing Super Smash Bros. Brawl, Mario Kart and More at Arthouse’s Teen Night video game competition (with prizes) 6 pm. Both events are FREE, but, sorry, you’ve gotta be a teen for teen night.
