This application reads a specially formatted text file full of words and their meaning and displays each and every word for a duration selected by the user. This is very much like a flash card application. It's called JapaneseAutoPrimer, because I wrote it for Japanese, but any language works just as well.

JapaneseAutoPrimer.py Sample:

position_change = 0 #the value indicates how much forward or backward to move in the list
