Having the world of art at your fingertips is awesome, and it’s such a bonus to be enjoyed when it’s useful. I’ve recently, finally gotten around to reading Larry Niven’s Ringworld. I was wondering if my visions of the characters described were close to what others had depicted, so I searched.
Nessus looks nice here in this illustration by John C. Atkeson & Mark Woolrich, and it’s pretty much what I got from Niven’s descriptions. The kzin, Speaker to Animals was close, but I pictured him looking more like Hoverball Cat.
