OK I will admit this discussion was prompted by @Atkinsar
's avatar, I do not recognise the minifig and was wondering what it is from, searched and got nowhere, and started wondering about others choices for their picture and what inspired their decision.
Mine I suppose is pretty obvious it is the Gold Chrome C3PO and it is my favorite minifig in my collection so far, being a massive Star Wars fan (OT) I had to have it. I think it summed up what I loved about Lego, the Star wars link, the collectable element, the artistic side..
So what is your Avatar picture, and what is the inspiration behind it (if you feel like sharing!). Oh and Atkinsar please put me out of my misery and let me know where yours is from (and would love to know why you chose it).
