How do i do this aniamtion?

I’ve got a question here …
take a look at the website : http://noisesingapore.com
my qeustion is how do they make the drawings come out as if they drawn on the spot ?

yeh you could try a fast moving jagged mask… I haven’t tried it but it might fool the eye enough into thinking it was written out…

As for the menus, they could, of course, have been manually animated… or perhaps a technique such as the page turn technique described in ‘Flash Hacks’ (http://www.oreillynet.com/pub/a/javascript/2004/09/03/flashhacks.html)

To be honest i think they look manually done… the speed the flick down goes would only require say 3 keyframes of the note as untouched, part way down and all the way down…
