This is a lava bomb from a shield volcano in southern Australia. This specimen is from my own collection.

Some of the columns seem to be clearly separated from the ones beside them i.e. there seems to be a clear gap between some of them - is this so?

...And its claws are as big as cups, and for some reason it's got a tremendous fear of stamps! And Mrs Doyle was telling me it's got magnets on its tail, so if you're made out of metal it can attach itself to you! And instead of a mouth it's got four arses!

I agree.  Keep in mind the columns shown in the photo have been exposed to elements and undoubtedly weathered.  Basalt columns form as the lava cools and shrinks- the most efficient cooling shape being hexagonal.  A few more photos from Giant's Causeway:

not sure which is better looking- these unique rocks or my daughter?

Basalt columns at the "Pipe Organ".  It's easy to see how these could erode down to the "steps" seen at tidewater.

That was a great link, Jim.  The Precambrian tillite, was specially interesting.  The picture was apparently taken by Jon Landvik, but one has to wonder if it was really John Wayne.  :)
