@AoKoori Nice! I think it would be even cooler if the ascii asset was not hardcoded in the skin but comes from an external location. That way folks can pitch in their fav cluster type markers and folks within a given org can share theirs.
Also looks like the tests are failing since this should default to the std k9s logo....

@derailed ok i've modified the logo source now it takes an url in the skin as a source to get the logo
