Im using knobman to make them and there are a few in there i must say i am proud of. Would it be better more flexible if i shared the knobman project files? That way you could change the colours, frames, sizes yourself and make them more suitable for your project?
Most of the knobs are just plain rip offs of hardware and software (PitCHERs knob is in there too! lol), from Voxengo, Albino, love philter, PEQ2, Arts acoustic, Alchemy and more!
There's an attachment of 2 of the animated knobs below (i hope! lol) to see what they are like.
Let me know what you all think!

EDIT: So they are being animated in Firefox but not in Chrome for some strange reason.
EDIT 2: I have attached a zip file with most of the knobs, they are set to 5 frame for fast loading but you will need to export them at a higher frame rate for a smoother turn unless you want at small frame rates.
