Learning to rig

I know Georg showed us how to rig last year but to be honest i completely forgot as i havnt needed to now how until now. I thought it may be worth while as for the post production project we wanted our bin to grow arms and legs and move so this could be worth while to me. It didnt actually seem very difficult but took a while of experimenting and just playing around to figure it out. the image shown does work but its just a bendy tube so nothing exciting. Anyway im happy iv learnt it as iv been meaning to do it for a while now =D
