Just checked it again: I dropped a TVpClock on the form - there is an issue with the Color property which defaults to clDefault, but this is not handled correctly. So, change the Color to something like clBtnFace or clForm, and you'll see the hands. Then I switch Active to true, and the clock starts.
You can also study the "gadgets" demo in the "examples" folder of the TvPlanIt installation.
