I have finalised the character design and i am pleased with it. I have been finding it very difficult to animate a tripod like character. I did a quick test in flash so I feel I have a rough idea of how to make it move but selling that sense of weight and getting across the scale of the tripod will be tricky.
Kirk told me to look at the Edward Muybridge. Below are some of his photographs. I found them useful with reference to four legged walk. If I can remove one of the feet I could possible use it as a three legged character walk. I also looked at the tripods from war of the world but found they spend most of their time hidden behind smoke and debris.
