WebCamMax – www.webcammax.com

Fairly cheap software that will allow you to add subtitles, pictures, videos and video screenshots (a selected area of your computer screen) to your video signal.
Costs $30 (about £16), but comes with 30-day free trial.

Stickam – www.stickam.com

This is the website that will take your video signal and route it to other computers.

VLC media Player – www.videolan.org/vlc

I use this video player in combination with the screenshot feature on WebCamMax to play videos as it is able to play a larger variety of videos that have been encoded using different codecs (e.g. Quicktime, DivX, avi, Windows Media etc.)

Blogger – www.blogger.com

One of many websites that offer free webspace which I’ve used to embed the code of the video player in order to provide a link that people can follow in order to view my video signal.
