animate icon in outlook toolbar

In early versions of Windows the icon for Deleted items used to gulp and shimmy when the user deleted things. This has inspired me to want to animate the Delete icon in Outlook.
At present I have replaced the X Mr Gates provides with the rubbish bin button face, which I have embellished with a few weeds, flies and stains.
What I want to be able to do is to animate this so that (a) when the user’s mouse hovers over it the flies circle the bin and a suitable sound effect plays and (b) when the user clicks it, the lid opens, something appears to be dropped into the bin, the lid drops back and the flies go nutso (and another suitable sound plays).
I would appreciate a few tips to point me in the right direction with this project as I am not too sure how to begin. I have standard Office 2007 software – and access to freeware!
