Just amaizing! The brightness in the middle constrats with the darkness at the bottom and the corners. The circles give a magical touch to the image, and some kind of "speed": it seems like you're falling, or moving really fast, each time faster in fact, through a tunnel whcih repeats its pattern when you go through the center of the cross made by the light blue light. I imagine all those shapes rotating slowly, quietly, while I keep falling, to end up in the middle of nowhere... or maybe I would reach a place, who knows?
(Gosh, what do I eat before commenting your images? xD)
