Damn, I should have forwarded you the invite to our seasteading social tonight, I don't think you're signed up for any of the lists. There were lots of Ephemerislers there, I bet you could've found someone to collaborate with if you are still looking. And it was just a cool party, at this great pad in Oakland. You would have had fun.

Re: waves, the waves on the delta are very small. Ripples, really. Not sure if that's sufficient for your idea.

Really cool that you're working on this stuff, there are a few cool platforms/boats I know of in the works, but not a whole lot of other art. yet.
