Stephen,
Does Richie still have a website? His old mac page no longer works as far as I can tell.
I did find this website which has some great photos of the actual island and Richie. http://www.sambarcroft.com/pages/Spiral/spiral.htm
The photo linked here is from this website: http://www.sambarcroft.com/ where you can find many more photos.
Sorta reminds me of the floating man made Uros Islands in Lake Titicaca in the high altiplano of Peru, cept those islands are made out of reeds.
If you stay on the island, let me know how it is. I might like to visit Richie. Also send me some photos if you take any, and if its ok, I will post some on my photos page!
Regards,
