The dance is called Taurus. It was made by my ballet teacher some time in the 80's, and I've performed it myself once, at a dance camp the summer of 2002. It is my favourite dance in the world, and will always be.
I had a photo of my sister and two friends dancing, and I kind of copied it, but turned the girls into fairies instead... Changed their hair and gave them wings. So typical of a fantasy-freak like me. :)
Wish I could publish the music as well, the song is lovely!
