Coming across this oldie-but-goodie Lainey Voom machinima reminded me of how much I love to shapeshift in SL. Some folks are cool with being "themselves", but I love the concept of being able to be anything:
Steampunk kitty. Intrepid reporter. Tiny terror. Curious traveller and shapeshifter. Buildings and fashion and exploring, oh my! Always a lady...always fun. What would be the point otherwise?
