I'm thinking about various artistic possibilities for narrow floating pathways -- imagine a long 4"x4" wooden beam that has floats under it.
- Achievement Lounge: There's a nice floating platform with some soft pillows, lights, and music, but to get there, you have to cross a long, narrow beam. The beam can be lit up in interesting ways. There's some nice psychology wrapped up in making the lounge a bit difficult and harrowing to get to.
- Sea garden boardwalk: Make a boardwalk that people can walk along... perhaps a hexagon-shaped grid of six triangles. The paths would likely be a bit wider (say, 6") for slightly more comfort. Place various glowing items in the water around the boardwalk. Some could be triggered by people's motion.
- Playground challenge: The boardwalk could have various sections that are difficult to cross (eg sections that rotate, thinner sections etc). It could be a fun area for people to walk around and explore.

There are all kinds of engineering issues associated with making this work ... how to make the beams float in a stable way as people walk on them etc. If I'm lazy (correction, expedient), I can buy a few
premade buoyant slabs for around $60 each. (careful, page takes a long time to load! :-) Alternatively, I could use much cheaper air drums, but those are typically barrel-shaped and a little more unwieldly for this sort of application. I could also take some cheap floats and put weight-distributing things (eg cardboard boxes) on top of them. Finally, the path itself could be buoyant -- a 10' long 12" PVC pipe could hold the weight of a person standing on it.
Oh, and if anyone is interested in helping on a project like this, let me know.
