Picture Puzzle: can you guess what it is yet?

Yes, well, I'm sure the sharper-eyed among you managed to figure out it was a representation of penguins, with what looks like a whale's tail-fin poking out of some water.

What makes all this that little bit more special is that it's a cake. A birthday cake to be precise. My birthday cake. And it was made by my wife.

Here's how it looked early today in its natural setting:

Okay, I hear you say - it's an irregularly-shaped cake made to look like an iceberg floating in some water with some plastic penguins stuck on top.

But the most impressive thing of all is that every damned bit of it is hand-crafted - and every damned bit of it is edible!

Here's another view:

And - because it tickled me pink - a close-up:

Mrs. G has done lots of "special occasion" cakes of this sort for many people over the years (having started with an African Safari-themed wedding cake for a niece some twelve years ago) - all with themes close to the heart of the recipient. But this was the first full-blown one she's made for me (based on the BBC's enthralling Frozen Planet TV series) and was a complete surprise when it appeared this morning. I've been watching the most wonderful creations disappear out the door with pangs of jealousy for years - and taken many phone calls from ecstatic clients praising eulogising my wife's artistry afterwards. But now I've got one all to myself. Until it's been eaten of course, which, unfortunately, won't take long: I've had my first slice(s) and it tastes as good as it looks (the penguins are particularly yummy).

At the risk of sounding uxorious, my wife - who began adult life as a silversmith - is a very talented person.

Thank you, darling. Best birthday present I've ever had.
