Belgian artist Heidi Voet creates flags, sculptures and masks from plastic bags. Thought to take in the region of 500 years to fully decompose, the throwaway items become the medium and means to explore the past 500 years of human civilization. In the main exhibition space hang woven flags of countries that no longer exist, underscoring the improbable endurance of the not-so-humble plastic bag. Elsewhere, she photographs various fruits whose skins have been exchanged with others. Punchy, powerful and funny: should be good. Opens 29 May, 5pm - 8pm
