Well, they look like spheres that have a bunch of lights shining on them...

The part that is probably different from what you are used to is a kind of "polar opposite" lighting method. That's where for every light there is an opposite one shining on the reverse side of the sphere.

That's instead of a light only just shining in one direction and illuminating one half of the sphere and leaving the other half completely dark.

With the polar opposite lighting, the darkness is more of a thinner equatorial kind of band rather than being a large area of darkness. That band does give it a kind of semi-iridescent type look, but that actually helps to perceive more details about the surface shape actually, because when a large area is dark it is difficult to get visual feedback about the curvature there.

So there's really plenty of visual information there that makes it possible to understand that is a sphere, at least for me anyway! I guess if you have a very ingrained idea that a sphere must have only a certain kind of light applied to it then it might seem odd though.
