I knew a young fellow once, who was studying to play the bagpipes, and you would be surprised at the amount of opposition he had to contend with. Why, not even from the members of his own family did he receive what you could call active encouragement. His father was dead against the business from the beginning, and spoke quite unfeelingly on the subject.My friend used to get up early in the morning to practise, but he had to give that plan up, because of his sister. She was somewhat religiously inclined, and she said it seemed such an awful thing to begin the day like that.So he sat up at night instead, and played after the family had gone to bed, but that did not do, as it got the house such a bad name. People, going home late, would stop outside to listen, and then put it about all over the town, the next morning, that a fearful murder had been committed at Mr. Jefferson's the night before; and would describe how they had heard the victim's shrieks and the brutal oaths and curses of the murderer, followed by the prayer for mercy, and the last dying gurgle of the corpse.So they let him practise in the day-time, in the back-kitchen with all the doors shut; but his more successful passages could generally be heard in the sitting-room, in spite of these precautions, and would affect his mother almost to tears.She said it put her in mind of her poor father (he had been swallowed by a shark, poor man, while bathing off the coast of New Guinea - where the connection came in, she could not explain).Then they knocked up a little place for him at the bottom of the garden, about quarter of a mile from the house, and made him take the machine down there when he wanted to work it; and sometimes a visitor would come to the house who knew nothing of the matter, and they would forget to tell him all about it, and caution him, and he would go out for a stroll round the garden and suddenly get within earshot of those bagpipes, without being prepared for it, or knowing what it was. If he were a man of strong mind, it only gave him fits; but a person of mere average intellect it usually sent mad.

Often interfaces are assumed to be synonymous with media itself. But what would it mean to say that “interface” and “media” are two names for the same thing? The answer is found in the remediation or layer model of media, broached already in the introduction, wherein media are essentially nothing but formal containers housing other pieces of media. This is a claim most clearly elaborated on the opening pages of Marshall McLuhan’s Understanding Media. McLuhan liked to articulate this claim in terms of media history: a new medium is invented, and as such its role is as a container for a previous media format. So, film is invented at the tail end of the nineteenth century as a container for photography, music, and various theatrical formats like vaudeville. What is video but a container for film. What is the Web but a container for text, image, video clips, and so on. Like the layers of an onion, one format encircles another, and it is media all the way down. This definition is well-established today, and it is a very short leap from there to the idea of interface, for the interface becomes the point of transition between different mediatic layers within any nested system. The interface is an “agitation” or generative friction between different formats. In computer science, this happens very literally; an “interface” is the name given to the way in which one glob of code can interact with another. Since any given format finds its identity merely in the fact that it is a container for another format, the concept of interface and medium quickly collapse into one and the same thing.
