Cayden Khoo , six, and Matthew Wyatt, five, from Sparkletots @ Eunos Block 629 playing with coloured sponge tubes at the Hands On exhibition at the National Gallery Singapore. The play space by Dutch group We Make Carpets was first exhibited in Melbourne's National Gallery, and adapted for the National Gallery Singapore's Children's Festival: Small Big Dreamers, which starts today. Featuring a special commission inspired by the life and practice of Singapore artist Lee Wen, together with other interactive installations, the festival aims to encourage children and the young at heart to dream big through art and play.
