it's addictive, i'd have spent the day if my battery hadn't died an hour in.. also it was gloomy out, with the sun up you could get some nice lighting effects without the extra gadgetry i used the snow on my third floor balcony. if your going to use a snow bank, turn off the tea lights or candles while excavating to avoid as scary andy puts it "the yellow snow" hope someone else gives it a go
It's too damn cold outside so I dug up a tunnel to fit in and keep me warm and a second (smaller) parallel one alongside and I put a candle in in between : )
