Building a large sphere, how to frame?

Hey everyone, I'm trying to devise a way to build, well, a Death Star prop about 5 feet in diameter or so.

I've been doing some small scale tests with paper mache and such, but my core problem is how to create the armature/framework upon which it will be built?

My only condition is that I have to retain the ability to access the inside in order to have it backlit. I'm planning on drilling pinholes through surface to light from behind, ala Star Wars.

I've contemplated chicken wire on the outer surface, but I keep coming back to my core problem--how to concoct a sphere and/or curved ribs around a core frame. And what that frame looks like. I keep running into basic overengineering issues here.

Any ideas, suggestions are greatly welcomed! Thanks!

Large hula hoops? Maybe 3-4 of them. I have some from the dollar tree that are at least 3 foot rounds, but possibly 4 foot diameter... Cut and then tape together combine together with duct tape to create a stable frame, and then use cardboard strips (also attached with duct tape) to make thin support ribs and then maché over the entire structure. That's what I'd try anyway.

Well, sorry the original idea didn't work out, but that is one nifty looking eyebal

I know we always tell ourselves that we should start earlier, but it’s SO hard to be building stuff in a garage in Houston in August
OMG... yes!! I've been working on props in my garage since June and it is horrible. I crack the door for a little air circulation and work in the middle of the night with a bug zapper and covered in bug repellent... you truly have to be a dedicated haunter to put up with being hot, exhausted, sweaty and dirty and covered in mosquito bites for months to knock out a good haunt build. :D
