The installation consists of a number of suspended acoustic panels (speakers, to you or me!) which each play a random pattern of one of several voices reciting the days of the week.
This may sound (ho! ho!) like a pretentious nonsense, but as you walk around the installation, the patterns, rhythms and cadences of the different voices have different effects, varying from a general hubbub to a hypnotic drumbeat to an insistent clamour.
I was amazed at how the effect changed depending on where you stood, often the smallest change in location leading to a dramatically different effect.
Overall, the effect was mostly one of curious, light-hearted whimsy and I left the ICA with a broad grin on my face.
If you're near the Mall, stop in and be diverted.
