The concept
Riskboard was a skateboard hack built from scratch, that punished mistakes. The premises that the board gets harder to use, the more you use it, to make it unpredictable and more fun, it uses behavior-shaping frameworks I later applied to digital products, this time inside a physical object.
The process
Concept sketch. I mapped the riding experience, built a working hardware prototype, and tested it with real riders to see how the mechanism changed the way people rode. Then iterated a few times.
