Reminds me of the event horizon gravity drive 
cool
reminds mé of the alien transportation device in the movie “Contact” (with Jodie Foster)
i like, but its not quite rite, do u have 1? the inner ring is moving to much, the verts attached to the middle ring, shouldnt change, the outer ring, slides around on the posts (i couldnt make it look that nice myslef) i really like it other than that
:<
Also it would as always be nice with beveled edges on the rings…
Keep on!
