I don't know about heroic, but it is a bit daunting. Originally, I was hoping the list was already out there somewhere. I started a Google spreadsheet with several hundred entries so far. It would be nice to incorporate small reference thumbnails of each (I have found "only" 700 or so at this point).
I did find the site mentioned above. Thanks for that!

The AGK site mentioned is great too.
