I am using a \"spinner\" NSProgressIndicator in my cocoa app:
I would like to display it in a different color so that it will show up well on a dark backgr
I actually have implemented clones of the spinning NSProgressIndicator that might suit your needs. They can be drawn at any size and in any color. One is a subclass of NSView, which can be used on OS X 10.4, and the other is a subclass of CALayer, which can be used in a CoreAnimation-based project. The code is on github (both the NSView-based version and the CoreAnimation-based version), and there is a post with some screenshots on my blog.
