Hi Halo Nation, I love this game, but as a physicist I feel that the image of light rings should be improved. Although the megastructure Halo rings are perfect, the light effects of light rings do not follow some laws of physics. For more information about light rings, check out this note in Science magazine about our research involving halos and the parhelic circle: http://news.sciencemag.org/physics/2015/02/researchers-create-laser-dogs-soap-bubbles
