by using my non existant magical powers shock
meh I used image ready in adobe photoshop.I just made two different frames one with a lighter color for the bottle and other one darker and put them together.but kmc sucks cause of the ziggy size limit thats why it looks slightly pixalted cause i had to reduce the color and other stuff.
If you dont have photoshop i'm sure you could do the same in paintshop pro just use the animation shop thingy that you get with it.
