A lot of people coming to BSD from other UNIX-like OSes don't know about systat, because in modern times it has always been strictly a BSD application. It started out way back on on TOPS-10. Unfortunately I do not have access to a TOPS-10 machine, but here is what it looks like on TOPS-20.

For the most part, it's maintained its historical look and feel in all the modern BSD projects, which may be why new people who have found it consider it a novelty. While being cute, the default display, 'pigs', is mostly worthless.
In OpenBSD, it's continued to evolve. A few years ago, an 'if' display was added, that shows per-interface network statistics and states, and some months ago the iostat display was updated to show more useful statistics in a format that is easier to read.
The latest addition is a display to show the status of hardware sensors, which I added because I was tired of typing
whenever I wanted to check how much battery life I had left on my laptop.
I hope that this comes in handy for people who need to do more serious monitoring with their sensors, or who want to take quick glances at what's new with the acpi change of the hour.
So, check it out if you hadn't before. One other thing I'd like to see is an 'all' display, like NetBSD has, which automatically flips between all the available displays. But I suspect that's probably a little too cute to be accepted in OpenBSD. :-)
Here are a few more screenshots.
