I found a very different looking blossom on my Inca Sun brug - at first I thought it was shredded.

I like it. Wait and see if you get more of these flowers. Maybe you can propogate some more plants then of that piece of the plant.
Isn't it just winddamage or something like that?
Beautiful looking flower!. It's probably a weather or environmentally related effect on that one bud. I had a whole flush similar to that on one of my yellow Brugs once. The next flushes were normal. I could never pinpoint the reason for that happening other than weather or its age. It was a young plant.
Upon closer examination, mine was more shredded than split into petals. As Jori suggests, wait and see what other flushes along that branch give you. It would be exciting to have a yellow version of Star Dancer around.

The blossom looked like it had just developed that way. Each of the parts of the petal were very symetrical, and I could tell it wasn't wind damage after I looked at it.
Beautiful flower. Occasionally, this flower form shows up in the fall on regular flowering brugs. I have never heard an explanation. Maybe yours will remain split. Good luck.
As long as it blooms, I'm happy - the unusual flower is just a bonus!
