"Where the mind is without fear and the head is held high; Where knowledge is free; Where the world has not been broken up into fragments by narrow domestic walls; Where words come from the depth of truth; Where tireless striving stretches its arms toward perfection; Where the clear stream of reason has not lost its way into the dreary desert sand of dead habit; Into that heaven of freedom it should be our intent. ( my adaption from Rabindranath Tagores famous lines)

Escott sliding Block Puzzle

Apart from the "Rush-Hour" type of puzzles there is the conventional one. One of the most exciting ones is the one invented by E.B.Escott, an American Mathematician in 1938. Martin Gardner said of this puzzle that "It is the most difficult sliding block puzzle "that he has seen. The optimum solution will be 48 moves counting each movement of one block as a single move even if it goes around a corner if the space is empty.
