An illusion-themed prop, eventually for Daz Studio/Poser, that I am working on in Blender. It's a work in progress. I still haven't designed the base. The center blade is actually two blades, side by side. When it is finished, the two halves should separate.
I have a concept in mind for the base itself, a sort of interlocking design where beams project on either side of each box (both sides), so the inner (blade) side of the boxes have support. It's easier to show than tell --
