Standard Time screensaver for Linux!

Thanks to Standard Time friend Dirk Dodt it is now possible to run Standard Time screensaver also on Linux! Please see his instructions below.

How to set up standardtime by Mark Formanek and datenstrudel as screensaver in gnome (tested with Ubuntu 10.10, written by Dirk Dodt):

* buy the DVD of this amazing art project at www.standard-time.com
* copy the movie st24.mov from the RESOURCES folder of the DVD to your harddisk (for me this was /home/ddodt/st24.mov, you'll have change the python script accordingly)
* make sure you have mplayer and the needed codecs installed (apt-get install mplayer w64codecs gstreamer0.10-plugins-ugly-multiverse gstreamer0.10-plugins-bad-multiverse .. I don't actually know which codec is used)
* create the two files in the locations specified below (you will need superuser rights).
* set the executable bit for the python script (sudo chmod +x /usr/lib/xscreensaver/standardtime.py)
* now, according to what you find on the web, you should be able to go via the start menu to System -> Preferences -> Screensaver and have the new screensaver available. However, in my case, the new screensaver only appeared after removing (apt-get remove gnome-sudoku) some arbitray gnome application and reinstalling it (apt-get install gnome-sudoku). Not sure why this is necessary but it it worked this way on two different machines.
* so finally: go to System -> Preferences -> Screensaver and activate the new screensaver called StandardTime

And here are the files you need to create (the dashes ------- are just for your orientation and don't go into the files)
