Hi
Viva is a small framework to define animation developed by igor Stasenko. It is used by Roassal2 for its animation. Now Viva is published in its own repository
MCHttpRepository location: 'http://www.smalltalkhub.com/mc/RMoD/Viva/main' user: '' password: ''
and published in the configuration repository for Pharo 40.

Looks good, pretty much what I had in mind for a basic animation framework. How about making the animated value more generic and independent of a timer, more like a "binding" source -> property binding -> target and an (timer-)animated binding timer as source -> property binding -> target As I was thinking about an animation framework I got the idea of some more generic components. The components I had in mind: Clock EventQueue Task Binding or PropertyWrapper Range (as a source for interpolators) Interpolators Transition/Animation ( connection of a source(timer) and property bind, together with a range interpolator). scaling/easing function (linear/quad/quadIn/quadOut) Clock, EventQueue and Task classes (maybe we have some of them already) may be usable for other things and are used here as building blocks for the (transition/animation) framework. (The idea is, to not invent a TimerFrameWorkClock/ TimerFrameWorkEvent / TimerFrameWorkXXX....) Do you know this Squeak (Morphic) Animation Framework ( https://www.hpi.uni-potsdam.de/hirschfeld/trac/SqueakCommunityProjects/wiki/...) ? I like how it wraps different property animation in different animation classes (AlphaBlendAnimation/ColorAnimation ...). (I wonder why it is nowhere used) And there is GLMAnimation, but I don't like how it is implemented. nicolai
