Basketball Shoes, Manta Rays & Basking Sharks
The larger scale, flying wing type plane is a ridiculously large ship (I estimated the wingspan as needing to be over 1000 feet) from the CGI modeled "Max Steel". The premise of the show was a giant plane that flew within an artificially generated cloud and literally swallowed other, high-tech aircraft. I didn't end up finishing out the open dock sequence, but the concept was based on some photos I'd seen of basking sharks and manta rays. I had to logic out the faux aerodynamics of having a giant scoop in front. So, I envisioned the backside venting open like a basking shark's gills open up to allow water flow through its gaping mouth.
It's nice to be able to design different things sometimes, but it made me appreciate the difficulty of balancing shapes, design with what can animate well, not that I ever really got a sense of how well they translated onto screen, but it was fun trying.
