speed reading activity?

[david at lang.hm]

one of the things that got me started reading well was that at an early 
age I went to a school that had a speed reading activity. it had light 
cardstock sheets that you ran through a machine that moved them at the 
appropriate speed through a ~4-5 line window and the student would take a 
quiz on what they just read.

I've been digging a little bit, but not finding anything like this 
available for the XO.

has anyone seen anything like this? if so could you point me at it?
