Hi Catch - Thanks for the compliment, although the lion's share of the credit goes to jayjay88 and Colonel Morphermor (as my sig suggests).
It started out as just a still of my G4 tower, with the phrase "Power Mac G4 - The Power to Destroy Everybody Else." Then Jayjay suggested that I do something with a little more attitude, something that reflected my level of fitness as well as my Mac Addiction, so I changed the still to the tower with my arm flying the bird coming out of the side with the phrase "Power Mac Girl - The Power to Destroy Everbody Else." Lastly, Colonel Morphermor took that image, animated my arm so it was waving the bird (intended for pee-cee users), and changed the colors and wording to what you see now.
Ta!
