Here's an old screen-saver using some graphics re-used (ahem) from Doom. Download the Zip file, unzip "doomed.scr" to your Windows directory and you're away.
After the loading screen, move the gun-sight with the mouse and fire with the left mouse button. Kill things. Every now and again the level will change and you'll get different things to kill. Any key ends the screen-saver.
Dos dedos mis amigos. As they say in France, erm, Spain. Or is it Mexico?
