How to show lens and absorber outlines? How to save a video?

[Andratos95]

Hello! Thank you so much for this absolutely amazing code, it is so fun to play with!
I just have 4 questions for you, because I am a beginner at Python and I am not sure how to solve:

1. I see in your example images in that you show the outline of the lenses overlapped on the simulation, but when I run the simulation all the lenses/absorber walls are not visible in the scene
2. When I press play, the code starts and the simulation begins. I do not know how to save this simulation in a vide format (e.g. mp4 format). Any tips?
3. How can I make mirrors?
4. Is there a way to make pulsating extended sources? I saw example 2 where there is a point source with amplitude modulation, but is there a way to make this for an extended source?

Thank you so much and have a great day!

Take a look at the new example4.py it shows how to save video and demonstrates the new visualization layer. Most objects are now yet equipped with a draw function yet though
