I guess 'Launcher' just inherited the default. Who can update those? only admins currently, though the club is not that exclusive :) so if you want I can make you one...

There are many visualizations that try to capture good and bad, but I distinctly did not want the visualization to be about this. It is about how context changes the shape. As a consequence, architecture does not exist without the context, and as the context evolves in millions of little ways, so does architecture. Constantly. That is all. The main goal is to support technical people argue when discussing with managers, rather than necessarily having a say about the value. But, here is a challenge: would you like to play with it and propose a different approach? Btw, the current implementation has 19 lines :). > In the mean time, I'm slowly discovering we have amazing software >> architecture visualisation tools :) >> >> >> They really are amazing :).

Perhaps you can get some inspiration of places to use Moose in on the humane-assessment.com site. In particular, on the blog I try to offer examples and stories for how assessment should change the face of development :).

If you remove it, the world as we know it will end ! Seriously, I've seen this before, I also asked the same question, but no one seems to know. Sven
