You’ve got a couple more entertainment options this weekend—both of them free and more than likely to be memorable.

The Moore Theatre will be tweaked and transformed from top to bottom by various performance, visual and other artists on Saturday for Moore Inside Out, a four-hour open house that promises to turn into what used to be called “a happening.” Among other sights inside the building: Graphic artist NKO has splayed the names of past Moore performers across a wall; an awesome aerosol painting by Weirdo extends a pop salute to the theater’s vanished opera divas; and Megan Mertaugh, of BASE Movement Theatre, is somehow commenting on waste with a multimedia performance in a backstage bathroom that’s been filled with 300 watermelons (ah, performance art…). A melon is yours for the keeping if you’re there to claim one at 8.

Sunday, June 21 from noon to 5 is the official meet-and-greet barbecue/potluck opening of The Corner: 23rd and Union. This prefabricated mini-city on a corner in the Central District is project creator and public radio producer Jenny Asarnow’s way to reflect on urban change without pushing any agenda. The site includes large-scale photographs of neighborhood residents by Inye Wokoma that have been installed on structures made of found materials by a collaborative team of graphic and visual artists (including NKO—whose aformentioned work is also at the Moore—Joe Martinez of Handsome Murals, No Touching Ground, and David Rauschenberg).

What’s touching about Asarnow’s ambitions is the interactive element: The Corner’s Web site hosts the voices of people who call in to muse on their part in the neighborhood’s past, present, or future (some of these stories will be broadcast on KUOW and Hollow Earth Radio). The voicemail component (877-R-23UNION) is hosted by hip hop artist Yirim Seck.

Rain or shine, both events seem worth a roam.
