This is my Device, and I certainly treasure it. It is for the Detection and Location of Interesting and Intruiging People. It has, in the last week alone, detected and located at least six such people.
The story of how it came to be can be found here:

While many of Edwards's descriptions are considered by some to be somewhat fanciful, I can personally attest to the veracity of this tale, as I both wrote the original letter and recieved his reply.
My thanks to Suzy and Mike for capturing the Device so beautifully on their image capturing contraptions, which are, I believe, electronic in nature, and thus must be very modern indeed.
