The basic idea is to go through the deck randomly (by pressing Next card), until
you can recognize all the glyphs. Click Forget once you are sure you know a card. Then it won't be displayed
as you go through the deck, leaving you to concentrate on the ones you don't know yet.
Press Reset to go back to displaying all cards.
Press the Label button to display the name of each glyph. Leave it on while you're
first learning; when you start to know the glyphs, turn it on only when you're stumped. .
Font will toggle between a serif font and Arial. The Arial letters have more distinctive letter shapes.
If you view the source for the page, you can modify it to display other sets of cards.
