These “animals” are super cool…

They detect water, they detect sand, they can store energy, they can count in binary, they can carry heavy loads, and even move with the grace of a living creature. Then you realize these are 100% mechanical and there are no electronics here at all.  They’re freakin’ WIND powered.

AMAZING Engineering work by the designer!
