Zack Hubert has taken my MorphGNT and built a GNT Browser that blew me away! It displays the text in the browser; hover on a word and the lemma and parsing is shown in a pop-up; click on the word and you get a graph of word occurrence by book with the ability to list all occurrences.
I've toyed with web interfaces to the MorphGNT for years but nothing even remotely as slick as this.
The original post was in the categories: morphgnt greek new_testament_greek but I'm still in the process of migrating categories over.
