Gift For A Winning Husband?

My husband is being really fucking awesome at the moment and supporting me in starting a business. Myself and everyone else have had our doubts, but for some reason he just keeps having this incredible confidence in me and I've never felt so encouraged. It's great. He's also really good at presents and I really suck at them. Anyone have any ideas? He is passionate about travel, transformational experiences, art, architecture, science, all the good stuff. I'm looking for less of a commodity item, and more of something he never could have possibly seen before.
