Basically, the way it works is that it is a frame of 2x4s covered in 3/4" plywood. On the plywood are holds. The plywood is resting on a horizontal 2x4 along the ground and held from popping off or sideways with some webbing. Half way up it is supported by more webbing. If I want to, I can lengthen the tops pieces of webbing to increase the angle of the wall, but the holds I have right now are too small to make that important. This may seem a little confusing, but here are some pictures that hopefully are relatively self explanatory.

	This picture shows the face of the wall and a brace on the right that goes back to my loft to stabilize the loft and climbing wall.
	This picture is of the "hinge" at the base of the wall.  Basically, the wall rests on a 2x4 that's on the floor.  The blue piece of webbing holds the wall on that 2x4.   On the left side of the photo you can see kicker section for starting your feet which is more vertical than the rest of the wall.
	Here's a picture of the back of the kicker.  It bowed in the middle, so I had to brace it with that 2x4.
	This picture shows the set-up for increasing the overhang of the wall. Simply untie, lower and re-tie the webbing.
	This is a picture of the side of my wall and loft. You can see my hang board on the side of the loft. To answer your question, I get in using those two sections of 2x4 that are screwed into the far post as rungs. Yes it's close to the ceiling. No, I haven't had anyone else up there with me, yet. [Update: yes I have, and it was interesting]
	Finally, there's the wall with me on it.  Yes, the drop knee and roll of the back are unnecessary, but they look cool, don't they?
