I just don't know. This maybe very ugly as space toys go.
But the design does have traction.
I've never seen it in action but I assume it jumps like a grasshopper.
I've seen something similar - at least walking - in old NASA experiments as covered in various Sixties publications like LIFE. There's even footage on YouTube of an early walking test in 1961.
(Sorry, can't find the footage at the mo)
So what do you think readers? Ugly? Authentic? What?
