No, it’s not for planning your iteration in the shower. Sorry.
Sometimes, you just can’t get to the walls. Maybe the building police won’t let you put anything on the walls. Maybe there just isn’t the space, or your team isn’t located adjacent to a wall. Portable whiteboards, which are the usual guerilla weapon of choice in this situation, can block lines of sight and available light. And sometimes they get the building police excited, too.
One team decided to take matters into their own hands and create their own Shower Scene. The cards fit into little pockets designed into the shower curtain. Note the little suckers at the top which allow you to stick it up on any smooth surface.
Just one supplier for this product (shop around, people, and let us know where the bargains are!).
