A reminder that "big ideas" and "creative thinking" inhabit the world of science as much as art.

And ideas don't get much bigger than Darwin's. The Natural History Museum is running the biggest exhibition devoted to Darwin, called rather appropriately "Darwin Big Idea Exhibition".

Unfortunately for Darwin he lived in a time when he felt his idea was too controversial to make public; he described it as "like confessing to a murder". 

Perhaps this sheds some light on the nature of ideas - an "idea" only becomes a "big idea" when it makes someone somewhere very angry. "Big ideas" usually challenge people's perceptions and as such are always going to be controversial. This may explain why very few "big ideas" make it out of the blocks in the commercial world be it in advertising, design, architecture or fashion.
