Always wanted to own a Lamborghini but never have enough dough? How about making one yourself? This is what exactly Ken Imhoff did. He decided to just build one for himself right from his own basement! Using space tube frames and a host of other materials, a remarkably good replica of a Lamborghini was birthed but not without 10 years of effort. Guess the main setback is that the model is probably outdated by the time it is ready. So head on down to your local bookshop and grab a copy (if it exists) of ‘Building a Lamborghini for Dummies’.

An alter ego (Latin, "the other I") is a second self, a second personality or persona within a person. It was coined in the early nineteenth century when schizophrenia was first described by early psychologists.

The term alter ego is commonly used in literature analysis and comparison to describe characters who are psychologically identical, or sometimes to describe a character as an alter ego of the author, a fictional character whose behavior, speech or thoughts intentionally represent those of the author.

The characters Doctor Jekyll and Mister Hyde in Robert Louis Stevenson's thriller Strange Case of Dr Jekyll and Mr Hyde represent an exploration of the concept that good and evil exist within one person, constantly at war. Edward Hyde literally represents the doctor's other self, a psychopathic being unrestrained by the conventions of civilized society, who shares a body with the doctor.

The term and concept also frequently appear in popular fiction, such as in comic books, for the secret identity of a superhero, vigilante, crime fighter or villain. Related concepts include avatar, doppelgänger, impersonator, and split personality.
