Horizontal Block Extender

I hunted high and low for a horizontal block extender that did not require redstone parts extended past the second piston and this was the best I could find so far. Many designs on youtube no longer work in 1.5 and I spent hours trying to rework them to come up with a workable solution.

The tutorial for this design was a little quick for me so hopefully these stills give you a better idea of what the tutorial is showing.
