CodeSaver is a simple screensaver for Windows that can “type” the content of any text file on your screen when the computer is not in use.
The screensaver is open-source and the default setting is such it will display its own source code on the screen. Or, if you are in the habit of writing your to-do lists in text files, you can change the screensaver setting to that folder and it will print your pending tasks on the screen.
