[TheThinkTank] Creative solutions for handling/storing shop pumps?

We've got a number of donated, bought, and found floor pumps in our shop. A variety of brands, sizes, and shapes. Right now they just live in a corner, but they like to play the domino game and fall over themselves when someone goes to grab one.

Does anyone have any creative things you've done to handle this problem?

As always, pictures are great.

Thanks!
