A modest proposal entails transforming a closet space in which two possibilities exist:
One notion nostalgicizes retro-sixties television kitsch via Batman, in particular, the moveable secret bookcase which slides open to reveal twin Batpoles when either Bruce or Dick or even Alfred triggered the hidden button inside the hinged flip-top Shakespeare bust. An interior meant for storage hollowed out as disguised passageway acts as extended metaphor for the transfiguration of alter ego to something superhuman, or of mythological proportions. Such iconography transcends the popular cultural landscape to denote a historiography of place related to representations of Self versus Other. Recreating the set from this show casts a mirrored reflection that reverberates in perpetuity, image repeated in descending order.
Perhaps build a bookcase into the actual door left slightly ajar allowing a glimpse inside of video footage from actual show or reenactments of parts of different episodes.
Or install a handmade Japanese doorway curtain or ornate screen in front of three Chinese lanterns alternately flashing red, green or yellow light attached onto walls.
