This image looking down on a glass bowl is one of a series of fractal-like images I’ve made that are constructed by adding the initial image to successively reduced versions of itself.
The other kicker is that each of these images has something unexpected embedded at the innermost fractal single pixel level: my initials at the end of the doors in World without End, my face on a tiny train in Old Train Bridge, and a miniature of the outer courtyard through the door in Hotel de Sully, which (without the fractal) is located near the Place des Vosges in Paris.
In fairness, I must add that these embellishments are at the pixel level, and likely cannot be seen from the versions of the images that are posted. A large print of each image and a magnifying glass would work better, since only I can open the master file in Photoshop at a high magnification.
Can you see what is embedded at the end of the long tunnel down the punch bowl?
