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 have thought about it and you are correct, sir. I was retarded on that single point of Assembly being faster than compiler-optimized C++ for non-trivial applications.

However, I imagine that most of the beginner applications his brother will write at first are trivial.

Chances are that he won't see the difference in speed between even the slowest scripting language and C++, though, without intensive processing. Java would be a fair choice.
