Neat German article on using blink(1) with Raspberry Pi

The website Electrkonik Kompendium has created a detailed set of articles on installing and using  blink(1) on a Raspberry Pi.  They go through compiling the tools, using them to play around, and then hooking blink(1) to display system services status or user login state via cron.  Even though it's in German, it's pretty readable via automatic translation.
