I think it might be more natural if it had gradient below the line: http://i.imgur.com/8ku3OoL.png

I'm not sure if white or black gradient would be better though.

Thanks, this is a common suggestion and I've tried a version with a shadow below the line. It is far more distracting especially when you use the autoscroll feature (play button at the bottom right corner.)

If you want to experiment the source code is at https://github.com/rdwallis/MagicScrollWebReader

The line is an impossible challenge to design because the break between pages should be very obvious but also not distracting to the reader.

I find the already read text distracting. I would like everything within peek-ahead distance to be new text. Perhaps a white gradient below the line would work, or a three line tall moving white bar instead of the line.
