This was a sort of unexpected result. I layered OPI Megawatt?! over black, and it made an interesting antiquey gold color. I added some yellow glitter as a topcoat.
I then Konaded the black stripes on it and it looks vaguely Egyptian to me. I really like this one!
Update: I added an ankh and an Egyptian eye with my Sally Hansen nail art pen. The result is only so-so, but it was fun to do.
