Bernina has skins available for some of the their machines now. You can upload one of theirs or make one of your own. When I showed DH this feature, he wanted me to put this on my activa 210:
It doesn't look too bad. The problem is the legality of it as the photo belongs to someone else. But it is pretty cool. For all the Clone Wars quilting fans, this is for you!
DH said the buttons can act as photon topedo hits when you are sewing. Again, I'm pretty sure it's not legal to actually make this, but it would be pretty sweet.
I wish machines came with more personality. It used to be that your sewing machine was a fine piece of furniture and had scrollwork and other designs that made it beautiful.
