A bit off topic, A few years ago while visiting Canberra I was lucky to visit the Australian War Memorial and saw the "Man with a Donkey†or "Simpson and a Donkey†statue, I hadn't heard of it before, but I was impressed. It was of John Simpson Kirkpatrick (from South Shields) leading a donkey with war injured men in Gallipoli in 1914. The sculptor had hoped that the donkey's nose would become shiny from children rubbing it, it did! Yes a bit more ambitious than this project, but the idea that people are encouraged to touch and "connect†with it (I did!) Yes it's still early days Malcolm but good for getting some ideas out there, I also like the"safety lamp" idea. http://www.awm.gov.au/collection/ART40993/
