+## Old version using dlib
+The old version using dlib is no longer actively maintained, but if
+you want to use it, you can get it on the [dlib-stable branch](https://github.com/adrianiainlam/facial-landmarks-for-cubism/tree/dlib-stable).
+
+## Spin-off: Mouse Tracking for Cubism
+
+An alternative version using mouse cursor tracking and audio based lip
+syncing instead of face tracking is available at
+<https://github.com/adrianiainlam/mouse-tracker-for-cubism>.
+
+The main advantage is a much lower CPU load.
