Extractor/ Placer

I got bored today, and decided to make a device to pull/place blocks into a wall.
It worked, I'm proud to say.
It will also hide the block, making it less visible.
Its a good device, most of the tech is underground, you could make all but 5% of it underground.

In the screenshot I posted, you can see the top 2 pistons, I used wool blocks. If you are making a youtube series, and want to use my device, go ahead. It can be used to like show windows being pushed into buildings, and whatnot.

The results of me being bored. Thanks for viewing my post.
