Uumlbersicht Shell Commands on the Desktop Link
Übersicht is a Mac application that can display widgets on the desktop. There’s an entire cult around Geektool, which does the same, but Übersicht is raising the bar a bit for customization. It allows you to pipe shell command output to the desktop but format it using JavaScript and CSS. It looks nice.
There are many “widgets” already available if JS isn’t your thing or if you only have enough spare time to install a widget. If you want to build your own, read more about on the Github page.
