I was born in 1965 at Stanford Research Institute. I am a descendent of the trackball, invented by Douglas Englebart, and was brought to the world's attention by Bill English. I have become a staple for most of the world's computers, and my own descendants are of the ergonomic, 3D, gyroscopic, tactile, gaming and mousepad varieties - we have a large family, and live in most of the countries on earth now. We don't look the same any more, but still have the same pointing features to each other and are easily distinguishable by our design and physical features. Our closest friends are cables, USB's, buses, and software drivers that help us to work. We like being of assistance to your computer usage, and hope that our relationship continues for many more years to come!
