I also recall this 3D shell where your desktop was basically like an first-person shooter, where there would be a literal desk with files that you could click on, a media wall that would display your photos and so on. I forgot what it was called, but it was one of the coolest things ever. In reality it wasn't very practical, but it was still cool. I miss those days of crazy mods and customisation. Everything so locked up and dumbed down these days, in the name of "security".
