Finally found an answer to the question about a the cde screensaver I posted a few days ago...
You'll need to create a new directory that contains these two files, open a terminal window and change to that directory, and execute the runme.sh file from within that directory (./runme.sh OR ./runme.sh &). My two files are currently located in a /opt/switcher directory, but the exact location doesn't matter.
When you execute the runme.sh file, it calls the dtwmcmd file every 15 seconds and switches to the next CDE workspace. This time interval can be changed by editing the sleep command in the runme.sh file. It's best to setup the workspaces before you start switching, but you can still make quick changes to each workspace while it is switching (< 15 seconds).
Have fun with this... I know I will!
