# Blendalot - A Magical Animation System for Godot
**Status**: This is a very much work in progress repository. Very rough drafts of the design and API can be found in the
doc folder.
Blendalot is an experimental animation system for Godot that is currently in development.
Blendalot is an experimental animation system for Godot that is currently in development. One of it's core features is a
very flexible animation syncing mechanism that allows smooth transitions between related motions (e.g. walking, running,
limping , ...). This is done by using SyncTracks as described by Bobby Anguelov
here: https://www.youtube.com/watch?v=Jkv0pbp0ckQ&t=7998s.
Stay tuned for more...
