Keynote Remote was designed to operate as a handheld remote for Keynote presentations, offering presenters their current slide, build status, and presenter's notes if they had any. Built just after the development tools became available, it was a top seller and remained so until the functionality was rolled into the Keynote for iOS in a subsequent release.
I did the interaction design for this product, provided creative direction on the visual design, all in a startlingly short amount of time.
