redesign

i thought about redesign. whats the point in redesigning a lamp that already exists? there are millions of them, lamps that people use when they are intimate, and the best ones are either candles or ones they make themselves (the paper bag lamp). so why bother getting a similar effect to that of a candle? perhaps i want some similar themes and feelings shown by a candle, but not completely the same. i'm not amking an elecctric candle.
maybe its like writing a song which is completely different to another song, but the themes and feeligns overlap.
