Yes, I agree. The thing is; a wii controller wouldn't do for this because I
want to use it two handed and need quite a few buttons. I stopped by almost
every game and computer store in the city and most looked at me like I
should've known they would never stock anything like a tilt/acceleration
sensing joypad for PC so in the end I picked the only PS2 one I could find
to use with a converter. I think the reports on the PS3 one's drivers are
still a bit too scetchy. This one only has two axis and the quality is
fairly low but workable with the interpolation I posted about earlier. I'll
upgrade if I stick to this idea and something better comes along, maybe a
hybrid of a ready made joypad and quality sensors. I also play games so a
few controllers more isn't a big deal to me. :¬)

I'm not yet sure if shaking is "important to me" but I suspect so; most
people seem to want to go in that direction and that's always a good sign.
If PLORK with their Wii controllers isn't yet doing this somebody there
might want to try.

Oh, yes! The ones that are into electronic music but don't make it
themselves are best, I find. They aren't looking for conventions. It's also
a lot of fun for them and me. It's best when they point at the controller
and ask where to get one while completely forgetting that it's the laptop
where the sound comes from, that always means I'm on the right track, I

Of this? No, not yet but I'll try to get one (I don't have a video camera or
capable mobile phone myself). I have to tune this one some more before I'd
film it as well because it's really quite rough at the moment, not even
ready to set loose on friends yet, but I liked the idea and how it came
about so much that I just had to share. Getting "shake" in adition to the
other parameters and uses you can get from motion sensors is quite exciting
to me, at the moment.
