Maybe you'd be less talking to yerself if you'd give a brief explanation of 'on Twos'
oh, gee! NOW you want me to explain my jokes?

what's the world coming to?

:lol:
(pssst: in the old days when animators used onion paper to make keyframes over LightTables - tables with a light under so you could see through the transparent paper - they would only create every second frame on sequences that moved slowly enough. therefore, a second of animation could require 15 drawings instead of 30.
and as the really old stuff was done for film, a second was 24 frames which could be cut down to about 12 drawings.
At that point they would transfer the drawings by painting on cels [celuloid]. As this work was obviously very involved, anything that made it just a bit faster and more efficient was a good thing.
ergo, "working on Twos")
