You, As You Are — SimLee Da Eun

Turn a handle on the big wooden structure in Lounge 3 and you hear gears and unbleached cotton grinding together, mixed with sound streamed live from five spots around the museum. Some of it has been shifted down from the ultrasonic range a cat hears into one you can. The cat is Cat A, a fictional stray SimLee Da Eun imagines wandering Nowon-gu every day.

This is Buk-Seoul's yearly Idle Space project, so the three works sit in the second-floor lounges rather than a gallery. An overhead camera tracks you and lays your route over Cat A's on a round screen in Lounge 2. Most Seoul apartment complexes already have a stray everyone has named; Buk-Seoul invented one and wired the neighbourhood so you can hear her rounds.

The museum says the work is completed by visitors, so come ready to crank rather than stand back. Entry is free with no booking, the SeMA app carries an audio guide, and Fridays run until 9pm.
