I have added deep zooming to Fracton. As a part of the testing, I looked at the area along the negative x axis to see if I could zoom in and find a deep minibrot there. At low magnifications, the minibrots are located at points where some oval shapes intersect the x axis. Zooming in on those contained a minibrot so I tried doing the same thing in the area near (-2.0, 0.0). Not knowing what I would find or how deep it would be, I zoomed in for an hour or so recentering the image to keep the oval shape intersecting the x axis. I eventually found a minibrot at a magnification of about 8E107. There is a much deeper minibrot from the same general area on the FractInt Deep Zooming webpage. Can you guess how the two images differ?
