What Makes it Unique?

There are lots of practical reasons to use JUCE, but the most common compliment I get is purely aesthetic: "The code's just really nice!"

Open-source projects are often horrifying quagmires of ugly code that you reluctantly work with because they fulfil a purpose.. JUCE is different: I don't want people to use the library just because it does the job that's required – I want people to use it because they enjoy working with it!
