You'd understand my words better if you were me.
You unlock this door with the key of imagination. Beyond it is another dimension - a dimension of sound, a dimension of sight, a dimension of mind. You're moving into a land of both shadow and substance, of things and ideas. You've just crossed over into the Modern Algebra Zone.
Pleased to present for your consideration Mr. Modern Algebra, serious and successful scripter, who is not quite all right today. Yesterday and its memories is what he wants, and yesterday is what he'll get. Soon his years and his troubles will descend on him in an avalanche. In order not to be crushed, Mr. Modern Algebra will escape from his theater and his world and make his debut on another stage in another world that we call the Modern Algebra Zone.
