Below is the restroom wall at design consultancy IDEO. It represents an easily-replicable collaboration strategy that caught our eyes -; and, yeah, made us laugh a little too.

“IDEO encourages its employees to find inspiration by brainstorming ideas on the walls of its studios’ restrooms. Colleagues can build on the ideas of others in a light-hearted and playful way,” IDEO spokesperson Nadia Walker tells Build.

Walker adds that most of the company’s restrooms are not equipped with a chalkboard. Those restrooms are instead stocked with Post-It notes, which she says accomplish the same goal.

(Worry not about those who’d prefer to keep that time to themselves; IDEO still stocks magazines.)
