Kudos to the designers for turning a medical assist device into a beautiful piece of art that embodies the owner's personality. I can see this kind of customization catching on in a big way, and hopefully the clever designers and engineers out there will find ways to make it affordable.
This is what I think is great about engineering - it can make life better for others. It clearly has the potential to improve the quality of life for Kyron in this case, and very importantly raise his own self-worth.
People use wardrobe, cars, and just about everything else as a means to express their personality. Why not a wheelchair.
Perhaps, wheelchairs could even get some electronics customization. For example, the motor control could be adjusted and optimized for the specific type of activity. If someone primarily uses their chair for long distance, it could be optimized for longer battery life. If they're never far from a charger, but are constantly making small movements, it could be optimized fro that.
I think all of us went into engineering to make the world a better place, and what better way to give something back by helping to create systems which improve the lives of people while at the same time ensuring the look amazing rather than just functional.
