I'll second this. My "Hello World" is Pong. Whenever I want to test how well I know a new language, I make pong in it. It's relatively simple but will allow you to play with several fun things like animation and button mapping. Plus, you can show it to almost anyone and they'll look beyond its simplicity and think about the potential it represents - that you can make almost anything else if you wanted to.
The other direction you could go is implementing algorithms in various languages as a sort of mental workout, but that's a lot less fun.
