Thanks for the shout out. Here are some things I have done:
Tiddlywiki.com references an old introductory outline I did of the biblical book of Obadiah ages ago.
http://giffmex.org/experiments/obadiah.html#Table%20of%20contentsMore helpful, probably, is Gospel Bubbles:
http://giffmex.org/gospels.bubbles.html - has three phases: 1) visual maps of each Gospel, with passages organized by type of passage, and containing links to tiddlers for each passage. Done. 2) Adding parallel passages to the tiddlers of each passage. Done. 3) Tagging each passage with the themes, literary elements, people, groups and places found in that passage. Some of those are done for all. Most only done for Matthew.
Most of what I have done in Spanish is using TiddlyWiki to generate static html pages at
http://articulos.giffmex.org, so that does not showcase TiddlyWiki directly.
Others have done more with adding the text of the entire Bible to a TiddlyWiki file. Looks like someone already answered about that with an attached file. I have not done anything similar to that.
