KCad is a screensaver for KDE 3, based on KCad 1.1 (a old screensaver for Kde 2.2). KCad is a KDE Control+Alt+Canc screensaver.
KCAD is a very simple screensaver for KDE. In fact, it may remind you of certain OTHER evil screensavers. This was designed so that you can "trick" your Boss (in the BOFH sense) into thinking that you're running Windows NT on your workstation/server, even if you are running (insert UNIX clone name here). By default, it looks very KDE-ish, but you can make it look more convincing by putting the following text into the file $HOME/.kde/share/config/kcad.kssrc.
./configure --prefix=/path/to/kde --with-qt-includes=/path/to/qt-includes
- KUbuntu prefix is /usr
