here is the second time machine, i have added a second brass ring onto the machine.
first with its basic shape
inner ring to support the mechanics of the machine
shading around the ring and specular
i wasn't sure about how the ring would really work. i was thinking magnets to make it hover but i didn't know where i could place them so that people can see how it worked. so i gave it grappling arms to support the ring. keeping the grapple arm circular towards the base, allows it to rotate as well, i think this animated would look great.
