Here's the old discussion:

Thanks for mentioning, Simon - I'm very excited to see this, it's really
quite similar to my own work. 

Douglas, allow me to point you to my thesis from last year at
http://mediatum2.ub.tum.de/node?id=796958 
Chapter 3 in particular deals with very similar issues, I'd be happy if
you could give it a quick glance and tell me about your opinion. Or did
you already read it? The similiarities, as I said, are quite
striking :-)

There also is a cross-platform implementation of my concepts available at
http://tisch.sf.net/ and https://launchpad.net/~floe/+archive/libtisch .

One thing I would suggest as a future extension is something along the
lines of less monolithic gestures, i.e. compose them out of still smaller
primitives such as number of fingers, held time, pressure, distance change,
angle change etc. etc.
