A photo used in the blog post to describe how Plunk works.
Plunk lets you easily put together fun tests for touch screen targets on mobile devices. See where users are tapping on your mobile pages, then measure the success of your design or see if it's littered with bad apples. (Those can spoil the bunch, you know!)
ZURB is a close-knit team of product designers that help companies design better websites, services and online products (www.zurb.com).
