Combining an astronomy hobby with sundials, I wonder if anyone has thought of how a sundial on Mars or Venus might look (ignoring the thick venusian clouds for the experiment), or one on the Moon?

And what about designing dials for Earth that keep the different planetary times? So that one could set up a line of dials each keeping time on the different planets of the solar system.

This just popped into my head just now, so I haven't worked out any of the details, but I look forward to the response of anyone else who's willing to spend some time thinking about it.
