While I'm still hacking around on the first one (besides some other small projects I started with Grails), which is about getting rid of doublettes in my ical calendars I have, I wrote a little script to generate my (haha, currently only single paged) webpage from a contents file and a general template - more or less just for fun, on the other hand, even with a single page it's nice to have the contents, the css and the general page frame differed.
My script looks like this:
import groovy.text.SimpleTemplateEngine
