So here's a couple of interesting videos I've seen recently,
Rocketboom (yep I still watch it) has a interesting short analysing the different video production used in the democrats announcements videos for the 2008 elections (can't think of a better way to explain them). They also have a good piece about paper or plastic bags and some interesting facts about the internet
On10 has a long piece about the Pioneer DVJ 1000 which is a Digital CD/DVD turntable. The reason why its DVD is so you can mix video along side music. Now I've seen this a while ago but never actually seen it been used live before. Dj Ronnie G does a good job showing off whats possible. Now to be fair I wasn't blown away but made me rethink playing with Virtual
Dj 4's ability to mix video at the same time as mixing music.
Large multi touch displays with Jeff Han and Phil Davidson. And I want to archive the other interface stuff which people might have missed over time. Light tracer and Afterglow use laser pens to interesting effect, MIT have something where they use a brush called I/O
brush and Multitouch research.
