Te Papa’s forecourt may look as if it’s under attack by giant glittery space balls, but it’s actually the start of a two-year kinetic sculpture installation called "The Mimetic Brotherhood", by Peter Trevelyan.

Attack of the mutant glitterballs!

There’s not much kinesis evident at the moment, but once the installation is complete, expect the plinth-eating monsters to start pulsating in their full hydraulic glory.
