Gilt/Guilt is a speculative performance-installation with sculpture, scent and video elements imagining a late-21st century auction preview of the collection of the dynastic EoS 10^15 (Empire of Smoke quadrillionaire) family. Preparing to relocate into a luxury bunker, the family contracts an auction house to help them downsize. The installation is animated by performance-tours led by The Auctioneer character who addresses the audience as esteemed collectors. Participants travel through a multi-storied building that is transformed into a haunting cabinet of curiosity housing 100+ seemingly luxurious artifacts, many of which are created from a process of virtual reality sculpting, 3D printed in resin, metal and bioplastics, hand-crafted and painted to mimic the surfaces of porcelain, precious metals, and rare wood. Each object –rare scent bottles, ivory rifles, commemorative gunpowder horns, silk garments, bejeweled masks, and video documentation of estates– unveils how the quadrillionaires accrued intergenerational wealth through centuries of investing in spice and tobacco plantations and arms industries. The unparalleled opulence blurs fact and fiction to interrogate how the language of, and desire for, luxury and power eclipse painful realities of Indigenous dispossession, enslavement, forced migrations, and environmental harm in the name of Euro-American “progress.” An accompanying mock auction catalogue details these stories in a restrained, diplomatic tone. As the immersive experience winds down, The Auctioneer transitions into a facilitator supporting participants to reflect on ways to grapple with unresolved historical wounds that continue to shape our present, and in the process, subtly, yet powerfully, conscientise the audience.
