I don't know how active this community is these days, but I wanted to log in and share my living shiny dex compilation with you.
If you visit http://keyglyph.com/dex, you'll have a choice to see the shiny species I've caught by any means (Shiny Dex) or the chainable pokémon I've successfully captured (Chained Shinies).
I created this database for myself so I could see how much progress I'd made and which pokémon I had yet to pursue. I've been doing this for seven years now (egad), and I hope that eventually I'll be able to say I've captured every chainable shiny available in Gen IV.
Someday in the future I'll be putting calculations into it so numbers will tally automatically, and even further in the future I hope to have a searchable database of every single individual shiny I've caught along with their natures, characteristics, and so on.
Hope you enjoy looking at it, and good luck with your own hunts!
