I haven't worked with a cel/gyro data before, so I might be totally wrong here...

Then screenshots below are of me sitting, and tilting my head in various ways.

It looks to me like the Accelerometer is picking up tilt angles, and the gyroscope is showing acceleration. This is backwards right?

No, it's correct.
Accelerometer is picking up acceleration i.e. gravity. and will always show gravity/acceleration, unless the Muse is being dropped in free-fall.. or your're in space
Gryo picks up rotation and will show zero when not in motion.
