[Lazarus] Linux screen-saver written with Lazarus?

[David Taylor]

[First post, so I hope this is the right newsgroup]

I have searched for information about and a source code example of a 
screen-saver for Linux written in fpc/Lazarus, but without success.  Is 
this possible?  Could someone please provide a source-code example?  I'm 
not after anything complicated, just trying to make a digital clock 
screen-saver for my Raspberry Pi!  Lazarus is installed and working fine 
on the RPi at the moment.

Thanks
David
