During our holiday gavagement, we had on a terribly kitch "Yule Log HD" cable channel, which offers an endlessly-looping video of a fireplace and the enforced cheer of Christmas music. It struck me that someone must have made a GIF 'n' MIDI version of it, as would be appropriate for use on the internet. There are several, but Ted Martens went one better, with a screensaver! Good job, Ted.
Update: A non-pixelated yule log for your computer, from the archives.
