blender pro tip: every 8 to 12 minutes you'll notice two little men run across the bottom of your window. pay attention to their expressions: if the Dogged Man is in front, it's safe to save - however, saving when the Noncommittal Man remains in the lead will revert any change you made that day. for odd numbered versions of blender, the order of these effects is reversed. remember it with the handy acronym DMSWDITNMWKAOA (Dogged Man Safe When Divided In Twain, Noncommital Man WorK All Over Again)
