Since I got the Sims2 in January, 2005, I have learned to create custom clothing, hair, and eye recolors as well as custom floor, wall, and terrain paint. I got very bored of that soon and decided to start meshing. I did that and made some very basic objects at first, then progressed to animated ones. After playing around with new objects, hair, and clothing, I've decided to go even further and branch out into animating.
I've managed to put some new animations in my game (just testing still and all has gone well so far). So I plan on creating some new interactions, mainly for storytelling and movie making. So look out for some new animations from me in the near future.
