It's no illusion: here are two kinds of fun, one to look at and the other to play with First, blast your senses into the next dimension with some of the most awesome 3-D mazes, visual tricks, optical illusion designs, and see throughs ever. One image features a practical-looking contraption--but can you really build it, or is it an impossible construction? Another picture features three men walking into the movie theater, one after the other; can you figure out who's tallest? Gaze into a circular checkerboard closely could it possibly be pulsating? Or perhaps you'd prefer to grab a pencil and try some tricky trios, solitaire battleships, whodunits, word searches and wordworks, story builders, and other puzzles. Whichever you choose, a good time is assured.
