I have finally got something to post.
Here is something I worked on last summer. ( well not really, it is a rendering I did last night ) Keep looking, you'll see.
The challenge, make something out of one piece of 4'x8' - 3/4" Plywood. Sounds simple enough,,,one thing I added to that was I wanted to see if I could do it without mechanical fasteners.
Challenge on.
I have included a PDF of a drawing package that I made for this instructable. It has some of my original design revised with "as built" modifications.
Also included, DWG and DXF files of the profiles for anyone with a CNC mill or router. (I just noticed a rib profile missing, i'll fix that soon and replace the files here soon. Till then, if you know your way around a DWG editor you can "copy/paste" one of the other ribs and modify it very easily to reproduce the missing part.
Finally, STL files of a simpler but still articulating version of this. Available for those of you who are lucky enough to have a 3D printer and want to play around with this.
I if you download these and find issues, let me know I will be happy to try and resolve them
NEW!
Just added for hand cutting DIYers, a PDF of all the profiles 1:6 scale for 1/8" thick material of your choice. Just stick it down and cut away. Use mill board, fun foam, balsa wood, ply...the list goes on and on. enjoy!

I first sketched out some ideas and modeled some parts on the computer.
But then I really just started cutting.
The straight parts were cut simply with a table saw and jigs.
I printed out "size as" (1:1) drawings of some of the profiles for cutting. I spray glued my 1:1 drawings on to some 1/4" M.D.F. to make templates for flush trimming with a router.
For the circular parts, all outside cuts were made on a band saw with a circle jig, inside cuts with a jig saw. I did a few tests with a jig but found cutting free hand worked better for me.

thanks for sharing these pictures keep me posted.
Thanks!!!!!

Thanks for your feedback. You are correct 1' -6" = 1 foot + 6 inches or to say the same thing differently 18 inches or 1.5 feet or... well not really. remember 1foot is 12 inches.
If all of this is too confusing there is now a PDF of the drawings with metric dimensions.
Have fun, enjoy.
At first I thought "meh, just another laser cut/CNC project - well out of reach for anyone with a budget/standard tools".
You, sir, have some great skills.
I have nothing against CNC anything. I have been around that stuff for a while, it's how things get done these day. I often think how lucky I am, learning to build by hand but have been given a new set of tools in the way of computers, software, CNC and Rapid prototyping. Pretty go time to be making stuff.
Hey I just added a PDF file 1:6 scale of all the profiles so anyone with some cardboard and an sharp knife can make one. cheap and cheerful.
I thought I would put something out there, and get in the game. I have been on the sidelined here for too long.
I will produce a 1:6 scale PDF for you and post it here. I think that would scale nicely to 1/8" material.
That would make it perfect for your Ken and Barbie...or is that someone else I'm thinking about?
Good, I get inspired every time I come here. No, to engineer in a formal sense but yes in spirit. Making stuff is what i do for fun.
also keep an eye out for a new DWG and DXF with the missing part in it.
the only thing that i have to ask is 'is it less effective without a reflector?'
You should sell this as a kit.
Another thing you may consider is laser cutting the parts from thinner (3/8") plywood or some other material (e.g. bamboo, acrylic) and stacking them.
