You already have the page flip animation in Smalltalk, just look at Form and page warp animation. It allows you to go from a form to another. pd: I've implemented a Morphic-Animations pacakge, adding the bitmap animations as strategy objects for each animation. If there's interest i could decouple it from Gaucho, and post it. Fernando On Wed, Jan 19, 2011 at 12:13 PM, Torsten Bergmann <astares@gmx.de> wrote:
