Need some material & lighting suggestions

I was playing around with this at work the other day, but I can find any materials that make it look good. For the spheriod things I did some green glowing stuff that was ok, but then I couldn’t find a material for the surrounding cage that made it look balanced. Lemme know what you think.

Hard to say how they must be textured, this is a good opportunity for you to play with textures and color effects.
Great luck!

Probably some darker color then the glowy thingie.
