We have released a Youtube playlist collecting short demos of AiiDA (2 to 5 minutes each).
Here is the link: https://www.youtube.com/playlist?list=PL19kfLn4sO_-XDUeXu5jwUq9k7TId8mM0. You can get the Jupyter notebooks run in the demos from https://github.com/aiidateam/aiida_demos/tree/v1.0.
Enjoy playing with them!
