The clock is this way the X-closing application. Running the frontend
from an Xterm makes the log with an Alt-tab visible. The loop lets me
easily restart. (Actually it has a whole menu with reboot, hibernate
etc. options). The vnc script has a similar loop to restart it. The
extra xterm is there in place of a normal text terminal. The TV is
interlaced vga to scart, so I can't get a normal console other than
ssh.
