I posted this late because I completely forgot to take videos of my project (so I brought my stuff to class, since I couldn’t show it in the day), and attached the videos of everything working here.
I do get patterns on the wall, but I was hoping for stronger colors from the cels. Interestingly, the halogen bulbs don’t generate as strong colors through the cels as my phone flashlight.
In this version, the bars are parallel rather than perpendicular. This was accidental, but still looked good! You can also see that the nicest-looking part of the project is the part below the setup with the swirling shadows.
You can see the crossing bars on the wall.
The crossing bars do generate a feel of motion, which is what I intended!
