Mechanical Rigging: A Patio Umbrella

I decided that rigging an umbrella would be interesting, and so I've done a patio umbrella, it's available at turbosquid.

The hardest part was figuring out how to make the umbrella's arms work. I tried various constraints without hitting on anything that worked the way I wanted it to, so I put the model aside for a day and then it hit me at some point that using IK would work. So that's what I did. It works like a charm too.
