: Hi Tony,
: Nah, keep thinking like that. But do it while working at something.

: Instead of cement or plaster-of-paris (the grades used for medical and art
: purposes is fairly fast setting) why not make a profiler like a butcher's
: block? Make the moving blocks smaller, of course.

: Sand, damped with a temporary binder, would work as a impress medium but the
: surface would have to be fixed with something like lacquer spray. Maybe
: thin plastic would do as a surfacing. Just wriggle on the sand and leave
: your mark. Then pour plaster-of-paris into the impression, smooth the
: surface and use that as a working mold.

: I'd wear something bulkier than underpants or swim shorts, you'll need some
: room for the thickness of your paddling clothing.

: Some extra wild thoughts for you,
