Hi, and thanks for submitting. I don't really like any of these, because they don't conjure up for me anything analogous to the concept of silvershift as analogous to redshift. The logo should progress in size and shade of silver/gray from one end of the frame to the other. One thing I do like is the tiny spash of color in Entry 50. I have been asking for only gray to sliver, but a tiny little splash of color, as you have in 50, could be cool. I don't have a concept of where it should go, or even what color it should be, but the concept, in general, intrigues me.
