The top of the third pitch, at the start of the tunnel, it is difficult to see or hear the second. The route follows a corner and chimney system up the wall. In order to see my climber, I built an anchor and then, using the rope, extended the anchor to the edge where it was far less difficult to see and hear.
Some might argue that this system lacks redundancy. I'm not too worried about that as I can see the whole anchor to ensure that there is no rubbing and we never have redundancy in the rope while we're climbing with a single line...
This second picture was taken in Leavenworth, Washington on one of ourAMGA Single Pitch Instructor courses. The assignment was for the student to create a fixed line across a catwalk on the slab shown. This particular student didn't have the webbing or the cordellete to create a perfect SRENE anchor. Instead, he built a pre-equalized anchor with his rope. In this application, this worked really well.
In this picture, another Single Pitch Instructor candidate built a top-rope anchor, wrapping a rope around a boulder and tying it off with a double-bowline. In order to create some flexibility in the anchor he tied an figure-eight on a bite and clove-hitched it to the line going to the edge of his top-rope anchor.
This last picture shows a close-up of the figure-eight and the clove-hitch mentioned above.
Flexibility and thinking outside the box are two major tenants of climbing efficiency. One way to be efficient and to be flexible and to be outside-the-box is to use your rope for anchoring instead of other materials. Your rope is always on you and as such, it definitely provides an option that really shouldn't feel like it's that far out-of-the-box...

In the Tunnel Vision photo, do you have the rope connected secured to the gear at the top with a clove hitch? If I get this right, out of the frame to the right, you are secured with the rope to a typical gear or bolt anchor?
Using the rope to build the anchor is a good old-school technique. I always used to do this. One problem though, is that if you have to escape the anchor - well, you really can't escape the anchor. You'll have to build another one and transfer the load onto it. So use this technique for speed and when you have limited gear available. But in general, a cordalette or slings will give you more options if you find yourself in a self-rescue situation.
This technique is common and is not so "old school". This is used by professional guides on many, many occasions. The anchor is built using a cordalette or slings in a pre-equalized fashion. The master point of the anchor is simply then extended by use of the climbing rope, over or around obstacles. When escaping the belay the belayer is already then "out" of the system. Thus gaining the use of the entire climbing rope again is simple. Transfer the load onto the original master point with a simple load transfer technique. This photo just does not show all of the detail needed. If you are interested, take a rock rescue or multi-pitch efficiency course for better understanding with an AMGA certified guide or instructor.
your carabiner on picture 2s masterpoint is crossloaded...
