Those have been out for several months. You can get them directly from The Gathering Room Quilt Shop in KY (which is who created them). There are also a few other designers, myself included, who have Twister designs as well. The next few months there will be over 20 new Twister designs from at least 2 different designers and I've heard of a couple others that have some interesting designs coming out for all 4 sizes of Twister rulers/tools.
