There I was the other day, enjoying a beer with [lukecleland] when I chanced upon the idea that a standard cigarette type lighter would, with only a minimal set of changes be an altogether handy spirit level (for judging the horizontality of walls etc.). Surely an enterprising manufacturer could do the decent thing.
