Gamasutra: Tetris can be interpreted in many ways. Because it is an exercise in pure abstraction, Tetris has invoked all sorts of explications regarding what it could imply. People have likened it to the rat race and communism, or to the stock market crash of 1987. And that's okay. That's how we make sense of things: we attach meaning to them.
For example, I can distinguish the constellation Orion from the arbitrary mass of stars because I envision it as a huntsman raising a cudgel overhead in victory, or as if to strike. Furthermore, I can recall the myths of Orion -- how his skillful hunting threatened to decimate all animal life until the gods unleashed a giant scorpion to kill him -- simply by looking at this arbitrary mass which otherwise lacks meaning.
