Knocki is an interesting device that can turn any surface into a remote control. As the name of the product suggests, you can knock or tap on any surface that the Knocki is on, and it will translate into remote actions (which Knocki calls tasks).

Knocki started as a Kickstarter in May 2016, and it got successfully funded on July 2016. It raised a total of US$1,144,399 out of its initial goal of US$35,000 from 8,897 backers.
