One thing that's nice about sphinx-gallery is that you can use whatever CSS you want in order to get the gallery look you want. E.g., with a few small tweaks you can get seaborn-like gallery images (grey box misalignment notwithstanding...this only took me like 5 minutes)

I wonder if it'd be worth having a css folder somewhere that we could store sample CSS files to achieve different kinds of galleries. e.g., in there could be a seaborn.css file that would define the necessary changes to get seaborn-like galleries. What do folks think about this?
