I rarely trick out my desktop to be honest
(I'm a simple guy with simple needs....)

I've played around with conky & the various widget packages
but tbh, I've always enjoyed just a stock Gnome setup

so,
probably the most unexciting entry in the show & tell

No idea where I got the wallpaper from,
it's just a Gnome flaming foot
