Interactive screen saver using Qt?

All,

Someone asked this today and I thought it would be interesting to post here. On the evil Redmond platform one can create an "interactive" screen saver. I don't work on the evil Redmond platform so they explained this as a screen saver which is basically an application that does not exit from any ol' user interaction. The user has to click on some defined exit button/link/etc.

In effect, until the user physically exits the application the computer is a single application machine.

The question which was posed to me is multiple parts.

1) Does Ubuntu (and YAU distros) provide such a thing as an "interactive screen saver" on all desktops?
2) If such a creature exists, at least in concept, on Ubuntu "could" it be written with Qt?
3) Assuming 1&2 are true has anyone actually done it or can they post a link to functioning code?

Thanks,

Boy, that better be some bug-free code. Having to hit the reset button because your "interactive" screen saver has decided not to be would be strong inducement to delete it and demand a refund with damages.

That sounds more like a lock-screen application than a screen saver.

But if you really just need something that covers the whole screen, just write an application that has one window that covers the whole screen?

Actually, the client would be quite happy with that. This is a sales demo/kiosk type application. In other words, the client doesn't _want_ people messing with the machines.

That does even more sound like just running a fullscreen application.

In a kiosk type situation one wouldn't usually even run anything else to reduce the "attack surface"
