Frustrated by the absence of HUD controls in Leopard ? ImageKit may alleviate a little, if you dare use undocumented stuff.

Add Quartz.framework to your project, open your NIB, drag sliders in and set their class to IKGraySlider (top one in the screenshot) or IKSlider (bottom one). The white spinner is IKSmallProgressIndicator, it has to be setup in code.

Thanks to F-Script for the spying around. There are more classes but I can't get them to work. Also, plenty of images in /System/Library/Frameworks/Quartz.framework/Versions/A/Frameworks/ImageKit.framework/Versions/A/Resources/
