This year "mash-up" is the theme of the European Media Art Festival in Osnabrück. If you happen to be in lower Saxony between April 21st and 25th you might drop by.
Also, drop into Mark Boswell's site Novakino for some beautiful and hallucinatory videos that are equal parts Vertov and Debord. More to come on these soon.
