Geesh GM!
Another good one ... Love it
Great idea of the rotating arms, I might try something similar as part of the big one thats very slowly growing in the bowels of my Xara animator
Yep! I mean bowels as it's becoming a right s...t of a job concentrating on the hundreds of little parts
To flip objects in UGA, you need to use the "Favorite Image Editor" button and take the particular frame back to PI where you can adjust it as you want and (save back to UGA directly).

I've never used the animating features of PI, prefer to make my frames and objects in PI, save as ufo's, then open with uga and use the copy/paste function to complete it. More personal to me I spose

Xara doesn't have tweening but Ulead doesn't have blending
