I like this logo very much. However, we have to explain the relation between SHR and juggling somehow (e.g.: SHR, where all components work in harmony.)

After the logo is well known in the community, it has big potential for more abstract icons (e.g. only the balls).

Well, I chose juggling balls because I think they can stand for the efforts of SHR offering as many (updated) packages as possible while staying fairly stable. I want to express that SHR is juggling pretty well between bleeding edge and stable with the coloured balls representing the variety of available packages.

Besides I think juggling balls look cool :)
