Google Forms revealed

After "war dialing" a custom form with parameters more then 180000 times, I've found the following settings that actually makes change to a form page. This page allows you to play with those settings, either on my or your own form, which will be loaded to the right.
I've tried to make this page very simple to use and to get the grasp of. All html, javascript and css used is contained in this frame and the form shown is loaded into an iframe. If you want to expierent further with it, it's yours to download and play with.
If you find cool things that I haven't discovered, please let it be known in the comments on my blog page, so it can be shared with the world.
Thank you.
And while I'm at the thank yous, thanks go to Gill Smith (and Ahab) for his excellent page, which make me see that there were cracks in the otherwise closed Forms setup - however, not all they documented was working and there were still many unanswered questions.
I hope some of those unanswered questions can be answered on this interactive page.

Active URL
Colors - Background color.

Form Language
Sets the language to be used for the Google generated contents
(Not working in Firefox 3.5.5)
Options - hide title.
- No matter what value, it will always generate a 404.
Form font - Sets the font family to be used in the form.
Insert more css via the font option hack.
   ;}.ss-footer{display:none    (Removes footer)
   ;}.ss-base-body{font-size: 20.0pt   (Changes font size)
   ;}.ss-base-body{padding: 20px    (Adds border)
If the item you want to change is allready defined in the css for the page (look at the source), then add !important to the end of the css statement, such as:
   ;}.ss-footer{display:none !important
Finally, to combine several css tags, use:
   ;}.ss-footer{display:none;}.ss-base-body{padding: 20px
Look at the resulting source to see what happens.

Note, that the use of # is not possible, this means it's only possible to address classes with your css, not #ids.
Additionally, it's not possible to specify colors in hex notation #RRGGBB, only in decimal valued rgb(rrr,ggg,bbb). The good thing is that it is possible to insert images - see the comments for more info.

Unfortuately all settings only work initially. If the page refreshes, such as if a user forgets to enter something and you get the "you forgot..." text, well then it will be in whatever language the server detects you to be using.
This is also true for the thank you message, which is hardcoded to go to a specific page. As far as I can see there's no way around those things. :-(
