So I just watched Goonies and I think someone should make an instructables on how to make a Data outfit. Answered

Just remember: Most of those gadgets are pure film props, operated via wires and fishing line and tubing and such from outside the camera's view. Building something that _looks_ like them, for costuming purposes, should be straightforward. Making them work... in general, forget it.

That sounds like a terrific idea! Make sure you take lots of pictures as you create the components, and ask someone to take a few pictures of you wearing the costume when you're finished (those will be great for you to use in the Intro of your Instructable).

Someone should. Since you're interested, that someone should be you...
