FlashGrid is an addon (a.k.a extension, plugin) for the popular flashcard program Anki. It adds the ability to drill by selecting from a grid (similar to the grids used in Rosetta Stone or Vocabulary Manager). It displays the Front of the card on the left, and a grid of card Backs on the right. Clicking on the correct card in the grid is equivalent to clicking on Show Answer in Anki.
