Here’s something very cool from a friend of Peter, a priest who lives as a hermit on a mountain in Austria, and goes by the nickname Donjojohannes on YouTube. This video shows him building his own oratory, including a very beautiful painted Gothic reredos, entirely the work of his own hands. His channel also has a huge number of short catechetical presentations on a wide variety of subjects in many different languages, which you might find useful. This link will bring up the full playlist in English:
