My favorites here have got to be the slow-motion replays, here and there, of close outcomes. One of you monkeys with video editing skillz (unlike myself) could probably come up with a pretty entertaining YouTube mashup using these little balletic snips. Will it start to catch on in the West? The crowds in Vegas last year seemed to be pretty well entertained, I think. This year's Kyushu Basho concludes tomorrow - hope that video from this will be posted soon. At the Grand Sumo Home Page you can watch tiny B&W Quicktime movies of historic matches.
