So apparently there is a browser plugin that plumbs all the way up to wacom tablet information like pressure and tilt and stuff. (wacom has official versions for osx and windows, and there's even a linux version: https://github.com/ZaneA/WacomWebPlugin)

Sooooo you can write webapps that do that, I guess.

I am curious: how many of you all out in lj land actually have a tablet?
