Excellent. I hadn't read the thread before as I figured Gyotaku was likely to be a fish I'd never encounter

I've got a scan somewhere of some old old instructions for making a fish
weather vane (fancy
wind indicator designed to be mounted on the roof). The gist of it is to catch a fish, then trace its outline onto a wooden form. At some point the whole thing gets covered in thin copper sheeting. Details like gill slots are copied from the real fish & stick out fins are added some how. The idea is to end up with a 3-D decorated, fish-shaped wind indicator that pivots over a traditional NESW direction cross. Sounds hokey but the result pictured (of a salmon) is quite impressive.
