For those who want a unique flag for their nation, province or city.
Tool 1: Scrontch's Flag Designer (Appspot)
This easy to understand flag designer is one of the first ways to get started. You'll notice this style all over the place. The colour palette is limited yet effective. Buttons show what each action represents. Your flag will be exported as an SVG file.
Tool 2: FlagMaker Jr. (Github)
A slightly more advanced flag maker. You can select more colours. And there are many more shapes to choose and combine. Your flag will be exported as an SVG file.
Via someone's else NS Twitter account, I discovered this fun political simulator on filteries.com.
Loads of sliders and options and graphs for you to play around with.
I had a go at it for 5 minutes, and this is what it looks like.
You can try it here: http://filteries.com/politics
NS forum thread: http://forum.nationstates.net/viewtopic.php?f=23&t=339984
I will be using one to display my election backstory. Perhaps some of you are interested in using it as well.
Besides parliamentary affairs, you could also use it to show yes vs no votes in your own governments.
