I haven't used a Screensaver since Windows 95. 😱
There is a clock screensaver that some people here use though, I don't know where you could find it though. Others are using Keycard, but you need an additional iOS device to use it.
But yeah, a lot of people prefer to turn off their screen with brightness controls, or just closing the lid on their laptop these days. I use the standby on my G5 even.
