What is a good first language?

My 20 year old brother wants to get into programming.  I want to set him up with a language that has these features:

1. Easy to learn, must have simple syntax
2. Immediate results, easy to make graphical and text outputs.
3. Fully featured language(I want him to be able to easily progress into more advanced stuff and not be limited by the language)
4. Fast(So he gets the idea of how powerful computers are)

I read the subject as
What the a good first language?
And the answer is Lisp, of course. Amusingly, Lisp is also a good first language. Meets all your criteria, as well as criteria you were too dumb to include.
