Fantastic- my cousin did a cake for her daughter's 18th birthday last month of Discworld balanced on the Great A tuin and supported by 4 fondant elephants. It was so wonderful we couldn't bear to cut it. I wonder if for my birthday ..well I wouldn't expect ALL of Middle Earth as a cake ..but Rivendell or Caras Galadhon would be nice ...
And for the matrimonially inclined how about Minas Tirith formed with a 7 tiered wedding cake.... Lal ..I think that is the way to go
