LipDub.in – The site’s name pretty much sums its concept, but in case you need a more detailed description, here it is: “LipDub.in combines lip synching and audio dubbing to make a music video. It is made by filming individuals or a group of people lip synching while listening to a song or any recorded audio then dubbing over it in post editing with the original audio of the song.”

To see an example of what users do on LipDub.in, see the two videos below; the first from Poland, Lip -dubbing Depeche Mode’s Just Can’t Get Enough; the second from the UK, doing Jet’s Are You Gonna Be My Girl.
