In thinking of ways to get an unstable arcing appearance to my son's blade (fit the story behind his character), I was thinking of possibly adding translucent glitter paint to the interior of the blade. In theory the glitter should give random "hot" spots to the light, while the thickness variations of the frosted clear should give random "cool" spots. Has anyone ever tried this? I have had luck using clear and matte finishes on prototypes especially SLA printed prototypes over the years, but don't want to ruin a perfectly good blade if someone has allready tried and failed.
