Origami

My parents-in-law received this and shared it with me.

I found instructions on the wayback machine, also known as the internet archive (which is housed in an old Christian Science church). I needed some help at the end and this video  helped me put it together.

I am not sure why some places call it a gyroscope ("a device consisting of a wheel or disk mounted so that it can spin rapidly about an axis which is itself free to alter in direction). I like the name modular spinner better.
