Yep, I could have used glovepie, but I wanted to format the data with the Arduino as it's just a test before wiring some servos

Not really : this way, you can capture events and use it on some prerendered animations, not realtime, so you can have real high quality rendering, etc...

It can't, but it can ear MIDI messages... ^^

You're so right ^^

Thanks. Here I'm controlling the rotations of my objects, but you can control almost any parameters. You just have to assign the Motion Capture Controller to the parameter, like X/Y/Z position of your camera.
I might make some more videos to show what is possible, but right now I'm trying to have 3DS read the serial port without having to use all those MIDI stuff.

Well, with this setup, I just used the "test" button, but I could have recorded every movement.
I'm currently working with maxscript & dotnet to simplify the process, and I hope I'll be able to release something soon ^^

Potentially (not with the wiichuck as there are some problems with the I2C adresses, etc... but with ADXLs yes), but there's a lot of work still needed on the 3D max side.

I saw that some people did the same using maya.
