Redstone Testing and Experimentation

This is a very complete redstone map that includes some basic knowledge, 2 arrangements of pistons in a 10x2 row, a clock timer, a regular stone generator, a cobblestone generator, two versions of the hidden staircase, a not-obvious version of the trapdoor, three deathtraps including arrows, flaming arrows, lava, and tnt, a timed lighting system, a lighting arrangement of piston-powered sunroofs, a hidden bookcase door, a dramatic timed lighting system, and a piston powered bridge across a lava pit. This is a very good map for redstone arrangements. PLEASE LEAVE SUGGESTIONS FOR ADDITIONS. ALL IDEAS ACCEPTED! PLEASE TELL ME ALL IDEAS YOU HAVE OR QUESTIONS YOU MAY HAVE AND I WILL ADRESS THEM AS SOON AS POSSIBLE.
