the official and the unofficial Ruby client for the BlinkStick are not really nice to use or "production ready"
So I created a ruby gem + a command line tool that helps me to set the color of the BlinkStick Square attached to my server.
You can find the code here:
Or just install via
gem install BlikstickSquare
and use like this
It would be nice if this new gem would be added to the list of the unofficial clients
