Tarting up the blog

I know I have said this before, but I really need to update and smarten up this blog.

One of the things I plan to do is change the picture. I was hoping to get someone to draw me a cartoon 'Stroppy' (sorta punky ), but that has fallen through. One option that occurred to me was to design an avatar and use that. I have a mac and so far can't find an application that does that, well only a head and I want a full body one.

Any ideas ?

Or any budding artists ?
