Hyperpolyglot – comparing programming languages side-by-side

I came across a neat website, Hyperpolyglot, the other day that does a really good job of showing off the differences in various programming languages in a side-by-side way. So for instance you can see how to do the same sort of thing in C++, Objective-C, Java and C# all right next to one another. Take a look and compare your favourite languages here.
