Yesterday was productive. Checks have arrived, bounced back from sick (after getting even sicker, that is), I finally did the "Gallifrey" circuit design for the Holocron and drew up my big attempt at the "Guardian" diffusion layer. Old-school; worked with ink (and lots of opaque white) on a drafting board because working through a graphics program was constraining my choices in the wrong ways.
While I was shopping for a new technical pen to complete the above I got an idea how to make the Wraith Stone work.
I've been pondering for months various schemes of multiple castings or fills to get the green inclusions. Well, after seeing some "ebony" Rub n' buff at the art store, I finally made the paradigm shift to accept casting the whole thing in translucent green, painting out the rest of the model, and dealing with the less-than-perfect way paint will interact with the internal lighting.
And actually, if I go clear instead of translucent color (using the LEDs to provide the color) I may be able to omit a casting stage and use the printed model straight.
So, yeah, I'm all inspired on this one now. I also came around on the qualities of the raised edge; a hand-worked look and resulting variation of thickness is fine. So cut the basic form from MDF then build up the details in Apoxie Sculpt. It's going to be built at about 3-up, scanned, and then printed to the actual smaller scale so not that painful to get the details clean enough.
