Focussed on the strong link between sound and memory is the project ‘LyreBird’ by Jessica Corr at Conflux.

‘The LyreBird is a pendant to wear while participating in Conflux events. It will record 1-2 minutes of sound at random times resulting in an audio souvenir of the city.’

It could also be interesting if the device had a little speaker as well and would not need to be connected to a computer to play the sounds. It might also be possible to write a software for mobile phones to make timed recordings and play them back randomly…just an idea.
