Nature’s video channel has put out two new short items for your delight.

The first is a film about Sci Foo, a very unusual conference held each summer at Google’s headquarters in California. This gathering of geeks is informal and unstructured; there’s no agenda until the first evening when the attendees collectively create one.

Nature’s Charlotte Stoddart went along to Sci Foo 2009 to capture its unique spirit on film.

The second is a trailer for the Lindau film series, which details an extraordinary meeting between Nobel Laureates and young scientists takes place on Lindau Island in Germany.

The films will be released one a week from 27 August. Watch them here.
