Some explanation about the origin of Blet can be found in Villegas's site. The word blet is a nonsense word coined by Malena Villegas, but it turns out that there is a town in France called Blet. We have also a paper on the math behind Blet, a modified version of which has appeared in the American Mathematical Monthly.
