Search for a couple of utilities

[Bob Alexander <bob@ngi.it>]

1) Is there some "overlay clock" that can display minutes:seconds over 
whatever other image is on my desktop ? I would use it while giving a 
presentation to ensure I do not run out of my allocated time.

2) Is there some simple way of displaying some nice "message box" on KDE 
? I would use it to show a message saying "External video 
enabled/disabled" while pressing Fn+F7 on my Thinkpad.

TIA,
Bob
