A well-wrapped start to the weekend, courtesy of Zander Olsen. The Welsh artist’s ongoing project Tree, Line comprises a whimsical series of land art installations that play with notions of background and foreground. Olsen swaddles trees in carefully aligned swathes of material for the purpose, perfectly joining them with their backdrops. The result is a clever reimagining of the landscape they sit within that prompts double-takes left, right and centre.
