Maple: very showy, colorful. Interactive! Presents puzzles in random order
and remembers which puzzles you’ve already seen. You can submit an answer, or not.
Requires cookies. (There's a also little JavaScript thrown in to make it more
user-friendly, but it’s not essential.)
Pecan: not as flashy, but you couldn’t have pecan
pie without it. This pie is ready-made—no clicking required!
Requires JavaScript and graphics.
Pine: evergreen. Plus, you can eat the bark if
you’re lost in the woods and starving. Requires... not much. Users of
ancient browsers, this is for you.
