Inspiration

Meet Flip Hattingh

Flip Hattingh is a South African artist that prodominantly works with woven paper as medium.

"OF REGRET" is a meticulously crafted paper-woven moth by Flip, currently on display at our Ghorbany Benmore antique retail gallery. The piece draws profound inspiration from the iconic movie poster for The Silence of the Lambs, which famously features a death's-head hawkmoth (Acherontia atropos). In a nod to the original imagery—where the skull pattern on the moth's back is actually composed of seven naked human bodies—this artwork explores themes of vulnerability and remorse. The intricate sculpture is masterfully constructed using Milano Craft paper, a material traditionally used for pattern-making in the fashion industry, interwoven with fragile, stained packaging tissue.

The structural cabinet features pristine, hand-polished gilt-brass metal borders framing five bevel-set mineral glass plates that invite multi-angle observation of the internal train. The face displays an elegant circular white dial adorned with applied gilded dagger markers and traditional Arabic numerals at the primary quarters, tracking time via matching dauphine hands.

The focal centrepiece is the advanced, temperature-compensating pendulum suspended in the lower gallery, utilizing twin glass vials filled with liquid mercury that contract and expand to automatically neutralize variations in ambient temperature, ensuring highly accurate timekeeping.

The structural cabinet features pristine, hand-polished brass metal borders framing four heavy, bevel-set mineral glass plates that invite multi-angle observation of the internal train and striking hammers.
