I've also made a Counter-Strike 1.6 Retroboard that is very interactive. You can play iconic sounds, view nostalgic configuration insights, take a nostalgic look at screenshots of community maps and check out a view very iconic easter eggs (plant/defuse bomb, shoot weapons, spray lambda logo, etc). There is also a link to the official AquaShell homepage that you can click to directly navigate there.
