This is a rather unsystematic review of the artist's experience of the art piece, gathered during a conversation shortly after the performance.

Richard Dedomenici agreed to take part in the piece because it would enable him to continue a walk he has been undertaking on and off over the last two or three years. Over the two days of the conference at FACT in Liverpool, Dedomenici planned to cover South East London, beginning north of the river in North Woolwich.

On the day, Dedomenici began around 10.00 am. Dedomenici's technique for tracing the boundary is to walk or catch a bus, scanning the shop fronts he passes for telephone numbers and identifying when the codes change. It appears the border often follows major arterial routes. Due to network problems he had reached the river at Woolwich and made the ferry crossing before he had the chance to upload his first purchase, around lunchtime. The walk takes Dedomenici through areas that are liminal in other ways. By the river there are large areas of bleak, industrial wastelands, partially re-developed and with few pedestrians. Away from the banks of the river, the route moves through the shabby hinterland between the inner and outer suburbs. Dedomenici reports that he was aware of being tracked as he travelled but, in retrospect, he found it re-assuring knowing that people were watching him as he moved through those areas.

On receiving a purchase request, Dedomenici says he felt an expectation for an immediate purchase; he found this onerous as it was not easy to find something interesting to buy that quickly. Reviewing the items purchased, and, more interestingly, the documentation uploaded to the map, we can see a determination on the artist's part to create an authorial voice, to account for the journey he is on and the situation he finds himself in. This combination of the temporal issue and the desire to find voice had a range of implications for the shape of the art work and the design of the system infrastructure:

• Expression: Dedomenici exploited fully the opportunities for expression, to the point that a short text input field in the upload form, intended as a brief description, he used for more discursive text. The field need to be longer, perhaps without a limit. The other media tools that the phone provided, a Nokia 6680, such as video and sound recording were only partially supported by the version of the system current at the time. Dedomenici felt this needed to be fully implemented as more media capacity would enhance the authorial voice.
• Phone Operating system. The phone runs Symbian v8.0 with the S60 user interface. The file management tool, used to select files for upload, was tricky to use. Image files had no thumbnails and the file naming convention confusing (admittedly, this was configured by Simon so could be looked at). Files also seemed to get lost. They probably weren’t but the point was the phone OS was simply too difficult to use in a live performance context. Dedomenici was also acutely aware of using an expensive phone in rough areas of London, so, given the time taken to operate the upload process, he waited until he was somewhere safe, such as a café, to upload media. The process whereby files were uploaded in response to purchase requests needs to be streamlined. One basic bug, fixed early on but typical, was that repeat uploads could be made to the same URL. This increased the likelihood of error as the wrong text message (containing the wrong URL) could be chosen, possibly one already uploaded to, and consequently two separate sets of purchase documentation plotted to the same location and customer account. In fact, Evans Studio is working Dedomenici to develop a fully automatic system moblogging system; in this any media file created on the phone will be automatically uploaded to a web server i.e. removing the need for the artist to worry about uploading and publishing after the act of creating the media. This is distinct from the One Pound Shop project but gives an insight into the type of requirements artists have for mobile technology – that the device OS should require minimal operation.
• Dedomenici felt that he had a personal connection with the customer through the purchase request. This could be enhanced, possibly, with personalised messages to accompany the request, but additions such as video calling would be too intrusive.
• The undertaking of two tasks, following the 0207/0208 border and buying items for a pound, was difficult. If the two tasks were more closely related it would have been easier and more meaningful.
