Thank you for this, wonderful break down of some amazing history. I have watched that demo many many times in my pursuit of human computer interface thinking.

Thank you for this, wonderful break down of some amazing history. I have watched that demo many many times in my pursuit of human computer interface thinking. I often wondered what happened to this piece of hardware… I still hold a deep belief that our current input methods are flawed(as amazing as they are) and we are in need of another leap forward. Anyway great read - thank you again.
