Best Way to Show Seasons?

I am trying to design a short visual for talking about the solstice or seasons in general. What I have done is just enlarged the Earth (Scale=5000), and put it in motion around the Sun. It does a great job of showing the terminator move throughout 1 year, however, it would be totally awesome if I had some way of showing that the tilt doesn't change, while the terminator does. Even just a line through the Earth model through the pole would work, otherwise, to my audience they don't see what's so special. Does anyone have a better way to showcase seasons?

Greetings Katy.

What version of Uniview are you running?

If you are running 1.5 this can be done by adding the poles to the earth under the properties menu. If you go to the Markers tab from there you will see the ability to add a marker by clicking new, selecting pole lines, select the color and size (3 looks about right) and then click OK. They will show up and will be a property that you can turn off and on. Make sure to click save so that it will save the configuration and markers for the Earth.

Under 1.6 it works generally the same way, except there is no properties window anymore, it is all in the library window. Other than that, the process is exactly the same.
If it's of interest, I have not put this on UCare, but for our own season presentations we made large, 3D poles:

You can download the module there. If you would like to change the color of the poles, you can replace the "stripes.png" file with any file of the same name. We used green & orange "Academy" colors, but you could switch to red and white just by deleting it and renaming "stripes old." We felt this had visibility advantages over the basic lines.
