Most of us have limits on what we spend for Christmas.

But in a world with no limits, what would you spring for?

Perhaps a trip to space, where you and your family could gaze down at the Earth? A diving session to watch great white sharks rip apart dinner? Or your own hoverboard, for cruising across your own specially designed track?

Whether you're interested in exploring the ocean depths or getting your hands on a technology out of a sci-fi movie, there's something here for everyone - with extraordinarily deep pockets.
