I was researching a future post (on the name of the Herculoids' home planet; it's turning into a loong one!) and I found this cool video on YouTube: a 360-turnaround of a CGI model of Tundro. Let's see if I can make the embedding code work...
Nicely done; it captures the style of Alex Toth's original design. I'd love to see this guy do a model of Zok!
