High quality example programs and commercial software

[Ashok]

Rather than asking where I can find good examples of software implemented in 
D, I would like to be more direct. WHAT are the good examples of software 
written in D? By that I mean, the software from the user standpoint is good, 
great actually, and the code is EXEMPLARY D, the finest example of D but not 
the contortionistic version. Am I making sense?

2nd question: I would like to see the list of commercial software that is 
written in D.

I have more questions but want to SEE D first, not just READ ABOUT IT in a 
newsgroup. As they say, a picture is worth a thousand words.
