I saw this, too, and was intrigued. The great thing is that you can start out with any size square.
I like the Quilt In A Day triangle square up ruler. I just bought the June Tailor HST/QST shape cut. I've also used Thangles.
For making HSTs from squares without drawing lines, try the Angler 2.

I don't know how to find it again but it was two weeks ago. None of these rulers work for long, I lose them or forget them.
