I think you are talking about the Fons and Porter show on 2/27/2010. It was on Kaleidoscope quilts. The ruler was called a Kaleido Ruler. They come in Regular(Large) and Mini(small). I purchased the large ruler and a book on Kaleidoscope ABCs by Marti Michell from Crazy4Quilts-shop.com. I have the Fons and Porter program on my DVR if you have any other questions.
