Just got into geek shenanigans, and for the post up there ^, you can rotate scripts, but I'm not sure how. It has something to do with imagemagik, and some other programs and such.
If you have no idea how/what thefuck is going on, then if you search it on YouTube, there's a three part video tutorial that helped me a lot.
Anyway, besides date&time, calendar, and weather.
What else could you put?
