Late addition!

Boiling.

I've known about boiling for a long time now and loved the way it looked, with boiling nothing is ever truley static. Big Trains - Staring contest is a absolutely PERFECT example of this. The "animation" is pretty much a still. Boiling makes it less static however and gives it some life.

Now although this isn't everyones cup of tea, i was at a loss when it came to still shots in my animation. I hate when nothing is happening on screen so i decided to add this boiling effect. Although it's a lot slower on Big Train and to be honest a lot more noticable there's still enough there to keep it "moving".

(Appologies for the weird twitch, Flash's exporting is failing a little).

Now i personally believe that it works better than having still frames, and in a way it a little nostalgic look back at hand drawn cel animation.
