To mark the opening of retail destination the Emporium Melbourne two giant floating cubes that use technology become mesmerising installations.

Created by global digital content agency tkm9, the first cube is a seven storey art-inspired projection on upper Swanston St.

The second is a 360 degree mapped cube that appears to hover in mid-air on Bourke St Mall.

They use the latest 3D projection mapping and feature a bespoke sound.
