Animated fire, candle flames

We have been snowed in this week and with the possibility of power cuts decided to get the candles ready. This gave Dave an idea, he had experimented trying to make candle flames in the software he has but it had not worked that well so he tried taking videos of burning candles, editing them to repeat nicely and then converting into animated gifs. I think that these animated candles work quite well and it also opens the gates for animations that are based on photos rather than constructing in CAD software.
