Just found these two sites that feature rather unconventional basses and figured at least some members may not have come across them yet. Interesting designs suggesting, at the least, that bass players have great imaginations (although are not necessarily individuals who place a premium on functionality).

OK, just to save anyone else a firm dressing-down:  Susan already told me she is NOT gonna build a Gumby-Alembic !

The Gumby bass was just a distraction so we could sneak a couple of fur-covered Elans through the front office!

How about that 3/4 sized  Alembic Series II  Standard Point with Clear Amber Lucite Wings and  4  pick ups ?

Okay, I can't NOT ask...
What is so weird about the blue Rick 4080?

Or any Rick 4080?  That is the bass equivalent of the BC Rich double neck the greatest one of all time.

Oh, so Dave, YOU'RE the one with the fur-covered Elans !

RE:  Ric 4080:  That one is my non-Alembic holy grail.  If anyone finds one for sale, let me know.  Xanadu (Rush version, or Olivia Newton John) will sound so very, very sweet...
