What's that design called? oil & mica swirl

[Zing]

Soapers -- my laptop died an ugly death and all my bookmarked soapy YouTubes and websites died too. Please help me name a design that I've seen. You pour a layer of batter, then a bit of mica mixed in oil, and repeat. It's different from a mica line. One image was black soap and gold mica. Do you know what I'm talking about? Whatchamacallit?
