Hey, here are videos of the demos of parts 1-3 of HW 4, along with links to the code. A link to the code for the 4th part is at the bottom. I turned out all of the lights in my apartment and put some bubble wrap over the LEDs for the videos. It doesn’t really “blend” the light necessarily, but gives a certain sense of space and diffusion which I liked.
