THX-1138 From the software readme: THX-1138 is the calculator you've always wanted, short of handwriting recognition. THX-1138 (pronounced "thex") provides a calculator and the ability to plot functions. I chose the name as a tribute to the character in George Lucas' movie. Free software and old SF movies do not compete, and I encourage everybody to rent the movie, but if anybody still wants to sue me, please remember that I don't have enough money to make it worth the trouble, so just notify me, and I'll change the name.
