My wife bought me the Toki Pona book for Christmas. It's a sweet
little constructed language (conlang) like Esperanto, but with
a different philosophy. The author, Sonja Lang, wanted a language
that would help her simplify her thinking. To that end, Toki Pona
has only 120 words in the whole language! A word like 'kili' can
refer to all fruits and vegetables.
It's really cute and a lot of fun. I know it's not very practical,
but it can be learned so quickly that the novelty is worth it.
There's a #tokipona channel on Freenode where I lurk, practicing
my reading. Eventually I'll have this silly little pidgin that
I can use with a few hundred other nerds.
