Dance Animations
You will find a wild variety of dance names in SL dance machines.  The creators make up crazy names, and then venues can also change the name you see in the menu. 


INTAN ANIS

DMC sells the INTAN Couples Ball, the most prevelant in SL clubs.  At their DMC Main Store, you can find any of these dances from an array of creators using the specific URL below.  TP to the entrance point, then move to that URL to find the vendor of that dance.    There is an outdoor playground that is even easier to use. 
If you have the INTAN Couples Ball, be sure to buy the "Intan Ready" version that DMC provides as an option.  That makes it VERY easy to load into your INTAN.
