I'm starting to think that ripped ply does have a lot of potential for cage construction. You sure see a lot of it in modern furniture, that's for sure.
I have another idea for a cage. Picture the typical 4x2x2 plywood cage. But now picture it built from 6 face frames built from ripped plywood. Picture those face frames built from fancy plywood with multiple plys so you can leave the edges exposed - again like you see in modern furniture. The 4' frames will be 'H' frames, the sides will be typical square frames. Maybe even put a 1/2 radius or camfer on the exposed edges to emphasize the plys.
Each face frame will be made with pocket-hole joinery. The pocket holes will be left on the exterior and plugged with a darker species of wood, maybe something fancy like purpleheart. The face frames will also be held to each other with pocket hole joinery.
Now the inside of each cage will be skinned with 3mm Sintra. Black or tan would look cool. Plastic glass track would be the same color as the Sintra skins.
I would guess the cage would weigh about 1/3 of a regular plywood cage, maybe slightly more. Actually, it would be about the same as a boaphile, but a heck of a lot more sturdy.
It would certainly be attractive, albeit time consuming to build.
Now if I could just get my table saw assembled...
