I've seen a few guitars with "built up" backs and sides, where the back (and in some cases sides) were laminations of contrasting woods for visual effect. (not laminated like plywood for strength). I'll add some pictures, but this is a visual thing I want to try on a future project.

Has anyone got advise on how to approach this in terms of process, best glues to use, etc?

The Red Queen by Randy Parsons

David Anthony Reid "Vaultback" model

(side note, I kind of like the applied patches on the outside of this one by DAR too, kind of a neat effect)

For the equal width "stripes" my inclination would be to laminate up a half-width block that I could then re-saw into book matched slices that could be joined together for the back. For the radiating / tapered lines I think I'd probably work with maybe 1/4" to 5/16" thick parts and build up the entire back, then thickness sand or plane it to the final dimension.

I have no idea what this might do the the sound, but visually it's really cool looking.

I'll be following this thread, I have no answers... but that second pic is fantastic. Like a bowl back mando. Beautiful idea.

Parsons' Red Queen is amazing! I am humbled. There are some pictures of the buildup of the neck and back on his website.

How is the binding in the Red Queen done? The mahogany and maple sections, like a big rope binding. I've seen this before in multiple variations. Cut pieces to width, depth and length, with the angle in the ends, then hand fit each piece to the curve of the top? Glue as you go and then work in the outer corner after it is all glued up? I guess the purfling is laid in and glued up first using push pins or the like to hold in place. Just guessing, never done it. Would not mind trying.

There are a few great posts over on the Delcamp Luthier's forum about Marquerty and Parquetry. I have also seen a couple good videos of Japanese masters doing Marquerty for boxes and such....

It's an art of its own.

The basic process is to make up "logs" of inlay pattern similar to how you build a classical rosette. It's just bigger. They then use a very special plane to slice off a veneer slice.... Maybe 0.005" or 0.010" thick. Then just glue it to the substrate, level, and finish.... Nothing to it ;) ;)

The Red Queen is amazing. There are pictures on his website that show the glue up for the back. Also a peek looking through the custom F-holes on the top showing the marquetry in the armrest. Simply an amazing look at out of the box lutherie.

Nothing to it laughing6-hehe
