I am a Tolkien/Lord of the Rings geek. I have:
-All the LOTR movies on DVD...the extended editions

-A plate collection or two
-Candle holders..one of Lothlorien, and two in the shapes of Gandalf's staffs..Grey & White
-Some jewelry..including Arwen's Evenstar, a leaf of Lorien (elven brooch), Evenstar earings, an elven necklace
-The One Ring Trilogy mirage...(the ring mysteriously hovers over the carousel...spoooky)
-an extensive collection of Tolkien books (not just LOTR)
I'm sure I'm leaving things out..only the carousel, movies, books, and candle holders are on display in my home, as I plan on moving in the near future...and of course I've yet to acquire a few things...like the pewter Gollum/Smeagol book-ends for starters.
Of course, this is not the only reason I am a geek, but it's surely a start.
