Arrow keys to change card. C to reset deck. Spacebar to change modes: Draw from deck, with 52 cards and no repeats, or Pick Random, with :O random cards. No Jokers. :P Oh, and it records the cards it shows so you can go back and see if you've memorized them correctly. Love that incongruous music.
Made for me to practice memorizing a deck. No, really. -.- (serene telepathy face). Draws pips individually instead of 52 unique costumes. Card draw is word play: this picks cards from a preset deck and creates them by combining distinct images to form a whole. Credit to Bicycle, a subsidiary brand of The United States Playing Card Company, for card design. Scripts by me.
