To use screenlets on a current Gnome installation you will need to install the screenlets package from your distribution’s package manager. After the installation you will be able to open the screenlets manager that will help you set any options, add more screenlets and launch them.
From here you press the Install button and choose the downloaded HAL 9000 screenlet that you can get from this webpage. There is no need to unzip the file. You may then choose HAL and press the Launch button on the top left and you got HAL 9000 up and running!
HAL 9000 will speak when asked, blink when mouse hovers and decrease/increase darkness according to the CPU load
You can set things like the position of the screenlet, speak time interval in minutes, position locking etc from the options of the screenlet. You may also delete the included audio files and replace them with your own to create a more personalized supercomputer villain.
