Clan Plaid's Acrappa has launched Oni Res, a fansite that currently contains all sorts of demo information as well as scripts and utilities to use in conjunction with the game. Keep an eye on this site--it promises to be a very useful resource for the Oni community.

Update: And scant moments after its creation, this poor helpless site was ruthlessly assimilated by the Collective. It's now hosted here by Oni Central, so change your bookmarks. (And go visit it again...it's acquired a pile of new info since we originally reported on it.)
