Theme tank, Need your help!

[Blinky]

I was at my LFS today and saw something I just had to pass on...
There was a type of quartz rock they had called 'zebra rock' - it's black and white quartz, striped, in layers. It would look VERY cool in a black and white tank.

really cool blink, I'll go look for some of that. I think my LFS may have some.
