Easter Egg 2011

I've been so busy this week that I haven't had time to get working on my Easter egg - my idea would probably have taken a couple of days like Feathers McGraw did.  I did manage to get one done though and in only a couple of hours!  I'm really quite pleased with the result and also with my first foray into animating stills.  I could do with a lot more photos next time as I kept getting focused on what I was doing and forgetting to take pictures.  A tripod might be handy too so that I could get more action shots of what I'm up to with my hands, but it was simply a case of not having time today.  Maybe next project I'll do a better job :-)  So how long did it take you to guess what it was?
