This device brings back many memories! The nuns at my school use to use this. They would tell all of us children to line up in a row-barefooted. This was rolled along at our feet to ensure that we were in a perfect row. I miss the tip of my big toe every day.
I wished I had kept an article that I read once, in Time magazine that said that with T1 speeds, the internet had reached its limit!
Thanks for the post!
