Cool! The title of this piece is very well chosen-- there does seem to be a kind of inherent optimism to the simplicity and roundness of the architecture and reflectiveness of the spheres that I can't quite put my finger on.
Reminds me of the teaser posters for that upcoming video game, "Destiny."
If my assumption is correct (And I am sure that it is) this is one of those "infinite" pictures. For the small ball at the top mimics the shape of the large one it is a part of. As with the smaller ball on the top of the small ball. This would go on forever, if not for certain limitations. If it was a .gif, however, It would succeed in hurting my brain more, as it would just keep getting bigger, and infinity would be represented before my eyes. The background really sets it off, adds a nice atmosphere.
