Interesting – the list doesn't show up for me, either at the reddit link, or on the right-hand margin of your blog (where I do see the list of your previous posts). Any chance it's only visible to you, as the admin?
Another one for the list is the Halifax Art Boat. Their published stuff unfortunately does not credit Dave, or name that it is a slightly adapted Triloboat, even though they worked with Dave in doing it. But it's a lot of fun, and has been used in interesting ways. Links are here and here.
Thanks so much for the list of links.
