[ubuntu-uk] 3D OpenGL screensaver (or running Picassa screensaver on Gnome)

[Rob Beard]

Hi folks,

A client of mine (a radio station) has got a PC attached to a plasma TV 
which goes through a collection of pictures of events that they have 
been to.  At the moment they are using the basic pictures screensaver 
which just works apart from the fact it doesn't have any fancy effects.  
Now the programme controller is really into anything and everything 
Google (Chrome, Picassa, etc) and he's asked if it's possible to setup 
some fancy transitions between the pictures (the Google Screensaver 
zooms in and fades nicely between the pictures).  I just wondered if 
anyone know if there was anything for Ubuntu (or Kubuntu) that did the same?

If not, does anyone know how to get the xscreensavers working instead of 
the built in Gnome screen savers (I see there is an OpenGL pictures 
screensaver built in), or if it's possible to tell the Gnome Screensaver 
to run a script as a screensaver (from what I gather this is the only 
way apart from using the xscreensaver to get the Picassa screensaver 
with OpenGL working on Ubuntu).
