After I posted a gauge sample with GdiPlusX some months ago, Rafael Lippert from Brazil adapted my original code and created this cool analog watch, using GdiPlusX and the ImageCanvas class:
Cool isn't it ? It permits many customizations, and you may use it as a sample to learn other GdiPlusX techniques.
You may get it directly from Rafael' blog, at: http://lipsil.spaces.live.com/blog/cns!9498DCF62578E128!192.entry
It's worth to spend some time in Rafael's blog and website - www.lipsil.com.br . I'm sure you'll find some really very neat utilities.
