GToolkit uses a completely parallel graphics stack to standard Pharo. The VM and library ecosystem are still there but the UI is rebuilt from scratch on a modern vector based toolkit.

The productivity of the GToolkit developers is impressive.

Is it demoed in some video?

I've been following their work for the past five years or so. They have covered a lot of ground!
