There is a bit of that in the 7 days of creation media, though I find it -- for my part -- a bit underwhelming. There is also a bit of that in the infographics.
But what I am suggesting is the ability to navigate those Bible passages that are particularly challenging to visualize visually. The explanation would correspond to the sections of the Bible passage.
For instance, 1 Chronicles genealogies. Display the text on the left and show the corresponding part of the tree (timeline style where you can zoom in and out) on the right. As the user clicks the next arrow, the text progresses through 1 Chronicles and the tree progresses as well. At the bottom, have a small snapshot one can click on to consult the larger tree (overview of the whole genealogy) and afterward return to the smaller tree corresponding to the section being read. (*)
Second example, Ezekiel's temple. Again have a large overall representation of Ezekiel 40-48. As one starts with Ezekiel 40 on the left, have the right display the illustrative graphics. Have also the snapshot at the bottom (a bit like maps appeared in the old map tool) to switch back and forth between the overview and the section specific illustrations.
Parallel passages should be cross-references but kept separate. However, the ability to overlay parallel passages or set graphic differences side by side would be useful.
Part of the idea would be that this functions as a reading help with a greater connection between the biblical texts and the illustrations. Illustrations would be sequential and progressive (for instance, add the high priests garments as they are mentioned and described). When one clicks on a verse, one would see a marker that highlights the corresponding part of the graphic.
* something akin to what I describe can be achieved in this particular case for 1 Chronicles 1:1-28 by (1) opening up the biblical people diagram "Family Tree: Adam to Abraham" and (2) listening to the ESV audio (pausing as necessary) while following in the tree. If you have not tried this yet, give it a go; I think you will find it refreshing. However, the Family Tree: Abraham only allows one to follow partly from 1 Chronicles 1:29 (for instance, there is only one level in that family tree for Keturah's descendants, see v. 31). One may be able to find the information scattered in other trees and media but it does not make for the kind of experience of the tool I describe above.
