Lindy hop + accelerometer + gyroscope data == pure fun. Lead's traces are blue, follow's traces are red.

Top plot: acceleration (magnitude) over the last 8 seconds of the dance. Middle, (left): frequency spectrum of the 8-second acceleration window; middle (right): frequency spectrum of all the data up to this point in the dance. Bottom: angular velocity around the vertical axis (available for the follow only). Positive values correspond to counterclockwise rotation, negative values give clockwise rotation.
