After working with the command line utilities for three.js I realized I was going to need a batch exporter for converting a group of 3d object files in one shot. So I whipped up an OSX app(ThreeConvert), that links to the three.js exporter python scripts and lets you batch convert .obj and .fbx files. Hope it comes in handy!

The OSX app ThreeConvert can be downloaded here. Also the source can be found on github.
