The drill consists of either walking or running on the spot, over a fixed series of parallel lines marked on the floor. Alternating legs are raised by bringing one knee to the height of the hip, bringing the foot back down again to its original position, touching the line lightly with the ball of the foot, before repeating with the other leg.
The exercise should be repeated, maintaining perfect form, 100 times.
As the drill is practiced, proprioception (the awareness of the relative position of the body in space and the strength of effort being employed in the movement) is improved over a surface area of approximately 1 square metre.
One’s own body can be considered as a sculpture in the round.
This video explores the variation in attempting to maintain perfect form over 100 repetitions, by translating my own body as a series of data points, manipulated in three dimensional space via the experimental RGBD film making process.
(RGBD is an experiment in a possible future of film making, where photographic data captured in three dimensions will allow for deciding camera angles after the fact, combining the languages of photography and data visualisation).
