So the things I'm most proud of aren't quite launched yet, but I work right now on a lot of electric mobility projects. Something like a charger for an electric car is especially fascinating because you have none of the cues of typical car refuelling (smell, sound, vibration) and you can create an entirely new metaphor and language around how that charging experience plays out with light, sound, haptic...
Often you'll have a client who says "I want my product to be smart and connected so I need a 5 inch touch screen on the front of the box" and its fun to show them an entirely different approach that delivers both a better user experience and also becomes a key differentiator for their brand.
