Usually, to animate a blink, we have to set up 3 keyframes,
or if we need a hold on the blink, we set up 4 keyframes (2 for the hold)
since a most charcters are supposed to blink a lot, i made a script which automizes these key creations. The best part of Blinky Winky is that you can use this script to create realTime eyeblinks in the 'play' mode.
