After a couple of years of thinking about it, I built a floating planter, similar to the ones at WDW's EPCOT, and set sail with it on the lake my parents live on. Disney was kind enough to provide instructions in a book titled Secrets of Disney's Glorious Gardens, but I departed from this book in some significant ways, for instance, by adding an anchor system that allows us to bring the planter to shore for maintenance. Also, in the video I build a hot-wire cutter to make the styrofoam circles of the planter, a cutter equipped with a motorized rotary stage that turns it into something like a foam lathe.
