I'm looking for a who's who list of projects(open source) that really illustrate the strength of the languages they are written in. Ideally the project should make use of some features of a given language that would otherwise be clunky or difficult to do in another language.

Ruby on Rails makes astoundingly good use of Ruby's pervasive dynamicness. I'm not a Ruby-head really, but I've done a substantial amount of Rails programming, and what it does with the language is mind-boggling at times.

Dynamic generation of finders is a very good example of this. The actual methods that find models in rails are dynamically generated the first time they're called. When the model gets a call to a method that doesn't exist, it parses the name of the call and generates a method to search the database. Rails "Magic" is awesome! – Seburdis Feb 23 '11 at 15:36

Boost::Spirit::Qi really shows off operator overloading and template metaprogramming in C++. The library can be annoying to use at times because it doesn't always give the best of error messages, but if you need to recognize a little language quickly it lets you build recursive decent parsers using EBNF style syntax without leaving C++ or using an external code generator.
