I don't recommend using a TV as a gaming monitor, UNLESS you find one that's been specifically designed to have low latency. You would also need a dedicated video card (unless the "game" you're playing is something like Sudoku! ? ).
I've always had a transparent liner that goes on the inside (to prevent water getting out during showering) with an opaque curtain on the outside.
That said, not all shower curtains are made equally! ?
BTW, I'm blaming this thread in advance of any weight gain I may incur, because I couldn't resist getting a pumpkin pie during a trip to Costco tonight! ?
