Not bad, if I say so myself. The blurred blob at lower left is my hand holding my little Kodak.
Thanks for sharing the evolution of your Kammback. I like your view out the back and have been considering building a removable Kamm tail for my hatchback that would allow a view out the upper 1/3 of the rear window. I am a little concerned that the step-down to the Kamm may not allow the air to reattach even if I have a level section till it meets the template. I will be watching your progress with interest.
