Matthew Baldwin @ defective yeti has done something fun:

I created the @textadventurer twitterbot to help myself learn the Twitter API. Originally it did nothing but tweet Zork commands, taken from a walkthrough. I was its sole follower.

Oddly, I really enjoyed seeing the text adventurer wander through my twitter feed every hour or so. And when he would tweet, say,”go north”, I would find myself curious as to where he was headed. So I eventually created the companion account @zork_i, rebooted @textadventurer, and introduced them to one another. Now they are playing out Zork I in its entirety.

Hilarious.

It almost makes me want to see what Twitter is like.
