Manifold learning in scikit-learn

The manifold module in scikit-learn is slowly progressing: the locally linear embedding implementation was finally merged along with some documentation. At about the same time but in a different timezone, Jake VanderPlas began coding other manifold learning methods and back in Paris Olivier Grisel made my digits example a lot nicer by adding the embedding of different dimensionality reduction techniques from scikit-learn:
