No, I haven't figured out what the Horcruxes are. As far as I', aware, they're the ring, the pendant, possibly Nagini, Tom Riddle's diary, the goblet, (was that Hufflepuff's), and something of Gryffindors possibly. I stand ready to be informed. Eager minds await furthur information!!
Yeah you've got it mostly. The diary and the ring have been destroyed. Hufflepuff's cup and Slytherin's locket are two others. BTW, Rowling gave us a clue as to where the locket is in "Order of the Phoenix". Did you catch it? Hint: RAB used to live there.
That leaves something of Gryffindor or something of Ravenclaw as the last one. Personally I believe the Ravenclaw object is the wand that sits in Ollivander's window. Remember? It was referneced only once in "Philospher's Stone". I believe that is why Ollivander is missing. I also believe that he was not kidnapped or murdered but is being hidden by the Order.
There is a theory that says that each House corresponds to the four elements: fire (Gryffindor), earth (Hufflepuff), air (Ravenclaw) and water (Slytherin). The theory goes on to say that each Horcrux is to be found in its element. The locket (Slytherin) was hidden in water. If true then the cup will be hidden or buried in earth (Riddle's graveyard? the caves under Gringotts?). Look for a connection between the Bones family and Hufflepuff's cup. Not sure what it is yet, but Voldemort has paid quite a lot of attention to the Bones family throughout the series and that along with their name makes me suspicious. If this theory is true, and I think there's something to it, then the fact that Ravenclaw's wand was suspended in mid-air in Ollivander's window is an excellent clue that it is a Horcrux.
Nagini might be the 6th Horcrux, in fact probably is (wouldn't it be a riot if Nagini turned out to be the snake Harry set free when he visited the zoo in "Philospher's Stone"?) but I think there is an 8th Horcrux. I think the last Horcrux is Harry's scar. I think this is why he has access to Voldemort's thoughts and feelings. I think this is the big surprise Rowling has in mind for the last book. That would make Harry the Gryffindor Horcrux.
One thing I really enjoy is solving mysteries and riddles. That and the way Rowling comes up with her names. Such as the way to enter the magical world is through Diagon Alley. To perceive her world you must change your perspective and look diagonally (Diagon Alley = diagonally). Or 12 Grimmauld Place. Grim Old Place. And then there are the running gags she has with the numbers 12 and 7, the color purple and socks. Kinda neat.
Tex:
Haven't you missed a green stage between White and Red (assuming a five stage rather than seven stage process)?
I didn't know that. Now that's interesting. In her books, green is the color of death. I'm hopelessly clueless about alchemy though. I know only the barest scrap and that's not nearly enough.
I only knew about a 7 stage alchemical process toward enlightenment with black, white, red and then gold being the final result. So green fits in after white? Do you know what green is supposed to represent in alchemy? I'm interested if you do.
