This work is called 'Hammers'

Eight pin hammers of  different

Sizes are mounted on an acrylic

Tube. The hammers are made

to bounce away from the tube

and fall back onto the tube by

being hit by small solenoids.

The solenoids make a clicking sound and

the hammers hitting the acrylic make a

slightly different sound almost

immediately afterwards. The hammers

are selected at random and there is a

random time of between 1 and 17

seconds between hammers  being

activated. Occasionally, at random,

all 8 are operated in sequence in rapid

succession, which  makes a clattering

sound.
