The Matrix Candle shows a realistic flame one two LED matrices. It's been powered by a LiPo battery. The brightness can be set in five different levels. To start the animation simply press the button. To change the brightness, press it again for a short time. To turn it off, press the button longer. The battery lasts more than 24 hours depending on the brightness and can be recharged by USB.
Is it based on this?
