Ducks
In Paris, at the OpenStack Summit in 2014, eNovance were giving away ducks as their booth swag. When eNovance joined the Red Hat family, RDO decided to continue this tradition, and has done ducks each OpenStack Summit since.
Here's a gallery of ducks from years past. (Please share your duck images if you have them!)
There's a blog post explaining the significance of ducks.
