Just to put in my two cents: I very much agree with you about lifting source code being a rather disrespectful thing to do. However, I'm not sure if this was bri's intention (although I could be mistaken). I took the question to mean the original poster was wondering how to create something like it herself as she asked whether anyone knew how it was made and bri told her to adjust it as needed.
That's why below I told the original poster to make sure she wasn't stealing someone's code. Besides that, source code is pretty easy to get as is and doesn't always translate well into a layout. However, it does show how things were set up structurally. And I think it's fine to use it for that reason.
But I suppose what I'm saying is: I'd personally find it weird if that was bri's intention as she's very good about making it clear stealing graphics and all is not cool over on her community graphix, but at the same time I'm glad that you've said that in case it was her intention or other members look at this post and get the impression acceptable to just snag code.
And... yeah. Mainly this whole note by me is just for anyone else who might stumble across this entry and go "I'M CONFUSED".
