Enthusiast Eric Harris-Braun has designed and built a fantastic ball game with a similarity to darts, which is much safer and more interactive. His "Das Blinken Bonken" is a wooden board that is divided up into sections, each of which contain a pressure-sensitive surface that allows them to act as a button. And thus the basis of the game, it can be treated like darts in that the user throws a ball at each section in turn - or other games can be created that require various combinations of impacts, such as those demonstrated in the following video:
The entire project is documented so you can recreate your own version, or perhaps be inspired for other games. Either way, check out the project Instructable to get started. And for more, we're on twitter and Google+, so follow us for news and product updates as well.
