it still took a few minutes for me to figure it out.

The fact that you took the time to figure it out is the biggest compliment, thank you!

(The original version is much more out of focus, I wonder if it would have been hardier or actually easier - perhaps the sharpness of the front image is too distracting? I'd like to have the skill - maybe the equipment to get the back image clearly and the front still out of focus. This trip was a good learning experience.)
