This weeks art Challenge is Vision of a Heron from Rohai

Rōhai (鷺牌) meaning “vision of a white heron” or “vision of a white crane” is a family of kata practiced in some styles of karate. The kata originated from the Tomari-te school of Okinawan martial arts. It was called Matsumora Rōhai, after Kosaku Matsumora, who was presumably its inventor (not to be confused with Sokon Matsumura). Ankō Itosu later took this kata and developed three kata from it: Rōhai shodan, Rōhai nidan, and Rōhai sandan. In Shorin-ryū and Matsubayashi-ryū this kata introduces Gedan Shotei Ate (Lower/Downward Palm Heel Smash) and Ippon Ashi Dachi. (One Leg Stance) It contains a sequence of Tomoe Zuki (Circular Punch) exactly the same as the one in Bassai, although the ending of the sequence chains into Hangetsu Geri/Uke (Half Moon Kick/Block).

In Tang Soo Do and Soo Bahk Do unlike most of its forms which can be traced back to Shotokan, their version of Rohai was based on the Matsumora version. Over the years practitioners have made numerous changes to the form including the addition of a board (or brick) breaking element, which can be performed using either a downward punch or palm strike.
