Candles are always good solid holiday gifts—no one will love them, but no one will throw them back at your neck either. But give your loved one a PyroPet ($22) candle this year and you may just win Christmas MVP. It starts out as a simple cat-shaped candle, but as the wax melts it reveals a sinister steel skeleton. Spooky. Designers Thorunn Arnadottir and Dan Koval are clearly a little disturbed, and that is officially now how we like our candles.
