In the classic trick, I pointed my MacBook's camera at the couch, and found out how my dog spends its day. This was a more eventful day for the dog than usual.
Tools: iStopMotion for the interval photos (every 6 seconds; this is a considerably edited-down version), iMovie HD for the editing (after an unproductive side trip to iMovie '08), and JDS Deinterlacer for a higher-quality slow-mo effect.
Music: "Tastes Gamey" by Fugue State
Dog: Lady Constantina Yarpadopoulos, our barky, bitey, sheddy, (and apparently sleepy) Jack Russell/Australian Cattle Dog cross.
