Eleanor Scicchitano has curated the exhibition The Unsolicited Proposals Unit at Canberra Contemporary Art Space, Parkes, ACT. Artists create unsolicited proposals throughout their practice; unbidden, they explore and present new ways of looking, and speculate about our past, present and future. These explorations revitalise mediums and materials, draw our attention to histories that have been overlooked and speak to a new future in the grips of climate change. The exhibition brings together works by seven artists from South Australia and the ACT: Roy Ananda, Jacqueline Brady, Saskia Haalebos, Bernadette Klavins, Raquel Ormella, Margaret Richards and James Tylor. It's on until February 28, 2021. ccas.com.au.

In this installation from Anna Madeleine Raupach, 25 clocks tick at programmed speeds based on natural, technological, and local cycles of time. Some clocks move to natural occurrences, such as the bogong moth's migration and hibernation, and the average woman's menstrual cycle. Countering these natural cycles are clocks accelerated to the rates of digital technology. Unequal Hours becomes a public clock that challenges the concept of singular time. Coloured ribbons connecting the clock hands continually circulate and tangle, creating a vivid representation of how alternate cycles of time are constantly intersecting. The exhibition is on display in the outside Gallery 4 at Canberra Museum and Gallery in London Circuit, Canberra City.
