Biophilia was not too "gimmicky", it was an ambitious but poorly executed project. Anyone can cut a record, but Bjork was also aiming to educate children about science and music, involve them in discovering their own creative talents, and put on an interactive show that included her usual attention to lighting and costumes.

Biophilia as a stand-alone record remains excellent:
