Clearly scuba can only get you so far, and while we've discussed submarine tours in the past, they are just jaunts.



What's the deepest you can actually go as a tourist, and what about if you were somehow able to charter a vessel (like I gather James Cameron is planning on doing)?


Question: How to highlight part of an image and blur the rest?
Answer: The first thing I thought of would be to use JS/jQuery to change the zindex of the element you wish to highlight to higher up (closer to the user) and have a partially transparent overlay appear .show() in jQuery (IIRC).

So you would have:

[viewer]


element to be highlighted
semi-transparent element
main content


Someone else will have to help you with the actual JS if you need assistance there.
