Earth Network

I had an idea and I was wondering if anyone would like to help me realise it:

I'd like to make a network that represents the connections between people I know and those that they know and so on. That's nothing new really and is exactly what facebook and its like do.

But what I'd like to do is make the nodes that represent the people out of porcelain and glaze them with an earth/soil sample* from where the person is from, and to impress something into the node to represent that person (for instance a lid from a toothpaste tube, a pebble, a leaf etc etc).

*this would have to be earth or soil and not shop bought compost as that is mostly organic matter and will just burn away rather than impart any mineral conent and potentially colour to the glaze.

They could then be arranged in a number of ways - location, connection by friendship, time of arrival with me  - any of the LATCH principles would be great.

If you'd like to take part please wing me an email/contact me by facebook - I'll need from you a earth/soil sample about the size of quarter of a ping pong/table tennis ball (please make sure its not poo of any kind, that's not funny!!!) and the location it came from, something to impress into the clay, your name and if you want a node for yourself a return address (also if you want your impression material back).
