Curam de Cara

Here's the kata Wankan

According to Squidoo.com:

Wankan is thought to be one of the oldest Kata still practiced to this day, a very short Kata, having been handed down in Ryukyu royal family for many centuries as a royal family Kata. In fact, the name of the Kata translates as "King's Crown","Emperor's Crown", or "King's Victory", which seems to confirm the link to the Ryukyu royal family.

Although Wankan is a short kata it has some unusual moves (at about the half way point), that are not repeated in any other Shotokan Kata.

Here's another version... not very good use of the hips:
