Here's a conference I wish I could make: Biomimicry and Architecture at Maho Bay on St. John in the US Virgin Islands. I've been there - it's fabulous. But even more fabulous is the agenda, which looks like an ideal immersion into the theory and practice of learning how to build from nature.
Maho Bay itself is kinda amazing. It consists of a number of environmentally conscious "tent" cabins on platforms and elevated walkways such that plants and animals can grow beneath. All the toilets are composting or other green technologies. Almost all materials for construction are green. And it is beautiful and a real "island" experience.
In particular, if you can schedule to be there during a full moon, be prepared for to get up for a spectacular 3am look at the caribbean -- you can look west towards St. Thomas and see the reefs glowing in the moonlight under the water, admist the transformed landscape of night.
