Don McArthur has a picture of Io posted. This, apparently, is what it would look like if you were, I dunno, looking at it from the surface of Europa or something. With binoculars or something. (In the right conjunctions, phases, etc., etc. People, please. No need to nerdgas.)
I can't, in all honesty, say it's eye candy. Because that would be the wrong food group. And you know how I get about taxonomy.
Anyway, it's cool. Go see.
