Iron Man Arc Reactor. The base is very delicate. Took me 3 tries to get one that would hold up to being assembled.
10 5mm Led’s in the ring. 1 10mm LED in the center. The saddles i wrapped with 23 1/2 magnet wire. Didn’t have any silver wire for the cross wires so i used some rechargeable battery straps. 6 pieces plus 10 saddles.

Some people use Adafruit NeoPixel rings as LEDs for their arc reactors.

However, the body in the tutorial at the link is pretty lackluster compared to @Wayne_Friedt design.
