@kiwimate thanks for the response. I will definitely check those stories out. My thoughts about this are general in the sense that as developers we often only use keyboard / mice. If you think of AV professionals though they often use mixing boards to get work done more quickly and finely tuned. So why are generic components not more readily available for general development purposes? Surely by using a potentiometer it could provide much more precise resolution than a mouse, faster and easier than typing in decimal numbers.
In a sense you answered your own question. Using physical input devices other than a keyboard and mouse could be expanded to many different industries.
I'm not really looking to commercialize this, most of my work is for personal interest. As far as my website, I am working on bringing a blog online for my technical non-artistic interests. I considered combining them however art people usually don't get technology and vice versa. It's a turn-off for people visiting a single website with diverse interests. My opinion is that its better to specialize when presenting information.
It's an idea and this is my starting point, to get input on possibilities. Perhaps I could hire someone to do it, but I enjoy the process of learning and adhere to the old adage that "if you want something done right do it yourself".
