From Right leg forward stance, the kicker takes an advancing step by turning towards the back shoulder, and pivoting on the right foot. When the left leg has come around 180 degrees, a right leg round house is executed. This can be done stepping, (putting the left foot down) or jumping as shown in the video.
To be more cross platform friendly I am trying out dropshots to embed the demonstration clips. You can still download a higher quality .wmv file below.

This kick is effective in sparring, but is also popular as breaking or demonstration kick. When working on this kick for sparring, remember to keep the back straight (maintain a good posture, do not lean back). If kicking with the right leg, after you begin the turn, reach toward the target with your left leg, do not begin to kick with the right leg until the left is in line with the target.
