Four decks of jumbo-index playing cards, for easy recognition on small screens.  Two decks have the suits in four different colors, and two have the traditional balck and red suits.  Tow decks have the traditional corner indexes, with the rank above the suit symbol, and two have the rank and suit side-by-side.  The latter are particularly suitable for solitaire games like spider, where the piles get very long, as otherwise, the jumbo index requires too big a vertical offset between the cards.

The decks have 52 cards, two jokers, and two backs.  Both individual cards and sprite sheets are providied in SVG, PNG and GIF formats.
