Sound installation. Like the Cat and Fiddle clock in Hobart CBD, the wobble boards activate on the hour every hour. This composition on demolition is ten minutes in duration.
For sale signs, modified windscreen wiper motors, chopsticks, drumsticks,
subwoofers, amplifiers, contact microphones, bass amplifiers, rubber, wire.
Wobble Boards – H69PM was exhibited in a group show at Contemporary Art Tasmania as part of HOME/LANDS in 2022.
Here is a smashing review by Jade Irvine.

In my face, in a public place, are bold sold ads. Everywhere. To me, these signs are a
visual reminder of experienced difficulty securing housing. The sold stickers boast
for faceless bags of money grabbing up Tasmania. The real estate state. Stolen
Palawa land. I can’t ignore them. These for sale signs are too loud.
For HOME|LAND, I have taken matters into my own hands. At night I confiscate the
signs and leave behind their frames. The tools I use are a Phillips-head screwdriver, a
torque wrench and a Toyota Starlet. Behold the stolen property signs.
The signs are composed variously of corflute, aluminium and hybrid plastic/metal
composites. They are durable and weatherproof, excellent material for constructing
roofing shingles. This was my original plan for the signs – to put a roof over a head.
However, in the act of acquiring the signs, I noticed that they are not only visually
loud, they also wobble and resonate. This loud wobbling comically disrupted my
smooth getaways. And so, this sound became my focus.
Here are the steps I took to achieve automated sign wobble.
Method One: – suspend sign
- attach subwoofer for rumble
- play low frequency sine wave through sign (40 Hz)
- attach contact mic to pick up vibrations
- amplify wobble
- adjust amplifier EQ to uncover resonant frequency
Method Two: – suspend sign
- rig up wiper motor to sign
- attach contact mic to pick up vibrations
- power on
- amplify wobble
