Very cool! It's funny, I picked up a female (Chocolate) several years back that had a little bit of this going on. She was the only one I had ever seen with it at the time and I thought it would be neat to try and breed it longer to produce a double-stripe. I had people laugh at me when I told them my plans for that little anomaly.
Since then I have picked up another female with much more double-striping, and now I see someone else has produced more of them. HA! Guess I won't be the pioneer on this project after all, though. 
Congrats on the find.... they are sweet!
