You might also wish to climb over an igloo without damaging the roof.

You can balance on the rungs with them in the horizontal position.  Not comfortable for a prolonged period but fine for short tasks.

yeah, I'd end up with a broken ankle, Sails

it would have to be a bloody teeny tiny igloo, Mutters

For crossing a small stream

Monkey bars for midgets?

Little known fact that those ladders were invented during WW1 to allow troops to climb down one side of a trench, cross the muddy trench without being slowed, and then climb up the other side quickly.

They didn't start being made again until the 1970s when some decorator  found an antique one and realised you could invert it for use as a platform.

oooh, good call Buzz

I'm putting the monkey bars in the igloo climbing category.

Or monkey bars for very small monkeys, say, a capuchin?

I would really like that to be true, Foolio.

For doing a The Professionals style climb over a car bonnet while taking a responsible attitude towards health and safety?

and it would protect the paintwork too with those lovely rubber feet

Portable gnome gallows?

Useful bit of kit when traversing the Khumbu Icefall.
