JordyArt the second idea of yours is a really good one as I have actually seen something of a similar thing done before, not by an internet group but rather by a mischievous teenager; let me explain lol. A friend of mine was going oversees on a group sporting trip and he just happened to borrow a small garden nomb (spelling) out of a strangers front yard in the middle of the night. He then proceded to take photos of the the object in front of famous landmarks such as the Grand Canyon, Disneyland and Las Vegas etc. He Then mailed the photos back to the owner of the nomb one by one with little notes saying things like " I am having a wonderfull time here, missing you heaps and wishing you could be here with me etc". Then when my friend returned home he in the middle of the night returned the nomb to the front step of the house it came from with another note attatched saying something like " I have had a wonderfull time and have been to some amazing places; but I have missed my other garden friends and you too much to stay away any longer. Please accept me back into your garden and I promise not to run away like that again". The owner of the nomb never knew who took it, but I bet they have one hell of a story to tell people at dinner parties and also have the photos to prove it. I know this has been a little of the track, but it just goes to show you what kind of fun can be had with the idea JordyArt has put forward.
