Been studying books and watching YouTube a lot lately and I think I'll try something I'll refer to as segmentarsia.
Some shaping of pieces...more like just easing the edges on some pieces. And, using different thicknesses without any elevating pads. I can see putting the Foredom to work, too.
Just glue the pieces at different elevations. Probably stick with a single species. Soft maple or poplar would likely work. And, use a lot of different stain blends. And dabs of paint. Might even use a bit of drywall mud.
Purists may (likely will) scoff but, it should be quite fun. Who knows, it may even result in a nice piece.
