Useless Machine

I do absolutely nothing on here, of course, but I thought I'd share this. It's a simple redesign of the useless machine made by Sethbling. You can see the machine in its full glory in the first episode of Bite-Sized Minecraft. A link to the specific scene is here:

There's another video by Sethbling which is his own design of the concept. You can see that here:

I think Seth's design falls flat in one area though. In Bite-Sized Minecraft, you can see the piston well away from the corner. Two blocks separate it and the second wall. Unfortunately in the actual Sethbling design, it requires the piston to be in the corner in order to receive power. Furthermore, there are lots of comments in the video speaking of how the design doesn't work, which because of its age is understandable and also very sadenning. Because of that, I have created this to fix both the requirement of the second wall and the fact that it is broken now. This is the design I have come up with. I think it is reasonably compact and really very fast.

I hope you all like it. Here are some gifs for you to see, the schematic (woollen) and the world download (both) are in the description, and of course let me know if you think it could do with anything more (such as a tutorial video or something like that).
