Several non-profit groups hail from abroad, including the Singapore Tyler Print Institute (STPI) and the Royal Academy of Arts (RA) in London. Established in 2002, with the support of the Singapore government, STPI is a gallery that presents innovative exhibitions and programmes. This year, it has brought to Hong Kong impressive three-dimensional wall sculptures by Chinese artist Zhan Wang. The sculptor smashed boulders of rocks into an explosive spectrum of rocky debris, reimagining humanity's fascination with the 'Big Bang Theory'. Zhan's Universe, created in collaboration with STPI, features celestial, metallic rock clusters assembled onto paper slabs made with mineral silt. STPI is also featuring Singaporean artists. The RA will present contemporary Japanese artist Mariko Mori at its Artist Talk event today, as an Asia Art Archive satellite event. The artist will be in conversation with Charles Saumarez Smith, secretary and chief executive of the academy, and Richard Chang, collector and trustee of the Royal Academy Trust. The discussion will focus on Mori's art and how it has developed since her participation in the RA exhibition 'Apocalypse: Beauty and Horror in Contemporary Art' in 2000. The RA is an independent, privately funded institution whose purpose is to be a clear, strong voice for art and artists.
