Burr Tools is a set of programs for solving some kinds of puzzles, namely puzzles that are made out of square, cube-shaped, spherical, or triangular units, and whose solution also contains only pieces aligned along those grids. The program finds assemblies for the puzzle and animates how you have to assemble for some of them. License: GNU General Public License (GPL) Changes:
