Zenga Zenga: Gaddafi's speech as a dance tune

In February 2011, after watching the late Libyan leader Colonel Muammar Gaddafi give an hour-long speech in an attempt to regain control, Israeli DJ Noy Alooshe acted quickly. Using video software and Auto-Tune, a tool to digitally distort voices, Alooshe spliced snippets of Gaddafi's speech with beats from American rappers T Pain and Pitbull's hit 'Hey Baby'. Within 24 hours he had uploaded the mash-up to YouTube. After just one week, the video had been viewed 2.7 million times.

IamJan25: Documenting the Egyptian uprising

The website collects images and videos captured by demonstrators in Tahrir Square, where hundreds of thousands of Egyptians gathered on 25 January 2011 to protest against the regime of then-president Hosni Mubarak. It is a collection of eye-witness accounts recording this significant piece of history from the point of view of the people on the ground. Containing over 7,000 videos and pictures, the website is the largest online archive of its kind.

Creating a video remix or mashup

A mashup or video remix is created by taking multiple sources of video, audio or stills and mixing them up.

'Found footage' (footage got from the internet) placed strategically with other images can create a new message through their juxtaposition. Mashups are usually short and simple – prerequisites for viral media. Repurposing footage in creative ways allows humour and irreverence to breathe new life into an issue.

Case studies


ObscuraCam is an Android application that allows you to obscure faces or objects in photos or videos to keep certain information private. It allows you to black out or pixelate certain areas of an image. You can also reverse pixelate, so that only the person is visible and the background becomes blurred.

The application also allows you to remove telltale metadata such as GPS location, phone make and model, and author information.

It was developed in partnership between human rights video organisation and the Guardian Project.
