Snarl is a cool notification system for Windows (similar to what Growl was for Mac). Its philosophy is simple: "When stuff happens, tell me". But that's incredibly powerful. Snarl comes with a lot of built-in notification sources and supported apps. And now the developers of Snarl have created a tutorial showing how to integrate our blink(1) USB light as notification destination.
Snarl does quite a bit and you could use it instead of our Blink1Control app if you wanted. (And if you want to use Blink1Control and Snarl, just replace blink1-tool with blink1control-tool when following the tutorial)
