Cool! Thank you :) I just wish it was plain SVG, I'm everything but familiar

with Blender and friends.
If you can do that, it would be great to commit these files to the Phat SVN.

Pixmaps are like binaries after all, and you got the sources.

Wow, brilliant and professional looking ideas in there..

Well, to me, the phat knobs are currently the only simple solution that look ok

in a GTK Window. They're not that alien, there is worse..

Theming, that's a problem. About scalability, I was thinking about rendering SVG

with Cairo (maybe several layers), but that may not be realistic.
IMO, Knobs will always be borderline in regard to GTK UI rules, and that's not

such a big deal, if you provide the proper keyboard shortcuts, etc..

I understand, that's quite complex. A simple solution could be to generate the

phat PNG "animation" from 3 SVG files with some python script. One could tweak

the SVG files (or intermediary PNG files) before doing so, adjusting borders if

needed, etc.. The result won't be scalable, but at least, a developer could

easily choose the style and size(s) he wants.
On the other hand, coded drawing may have the downside of fixed style and

anonymous look-and-feel. IMO, audio and music apps need eye-candy, they're not

just scientific instruments.
That said, there really are interesting GTK friendly ideas on your blog.

Of course knobs have downsides. But, in a window, knobs can be appropriate for

certain settings, and you can use sliders for others. It can give some graphical

balance. A window full of sliders may not be attractive, and may lack usability.
