I started my Necklace Park vennel mapping last week: meandering, climbing, poking, peering, moving on. I looked for gaps, cuts, ascensions and glimpses mainly in the city centre and discovered a long journey of slow promise.

I can feel a story developing. Wait and see....

create a participatory sound map of necklace park which can be done with the most lo-tec of recording devices like your mobile phone or a mini-disc player. you can record absolutely anything that takes your interest and/or you feel is representative of the location the sound is recorded. it could be a conversation overheard at a bus stop, an interaction with a market trader, a dog barking or your footsteps on a particular path.
the sound-tags get uploaded onto a map and can be listened to by clicking your mouse on a specific location on the map.
for an example of how this works go to:

The artist Alvin Lucier made a recording with thermal sensors attached to his body.The uninspired part is that he recorded a ticking clock. The tick is fed though an echo which speeds up or slows down depending on the body temperature of the artist.
So you could record the level of physical input involved in your activity, telling you if it's too strenuous or indeed a walk in the park.
