Are you kidding!?!? A hollow-body with a square-like head? That's way geeky! JMHO though...
Hollowbodies have traditionally had a rectangular headstock.
The Jack Casady Bass (yellow one) is in no way uncool, nor geeky.
but the other two...
yeah, you're right.
Why is the Casady any less geeky than the one on the top?

T40s are not geeky...they are heavy
Besides I thought natural wood basses were popular
