I see that Miniature Earth is doing the rounds on Youtube, with or without music. You can view it with Yann Tiersen's music, Mad World [disturbing suicidal lyrics, but a great version of Tears For Fears song, by Gary Jules] or with John Lennon's hymn to atheism and pacifism, Imagine.
This If the world's population were reduced to a hundred people was one of the first things I saw on the internet when I logged on in 1996. I hope those who view this video do more than appreciate what they've got and really do their part to make a better world. Though I guess we all have our ideas on how best this can be achieved.
