Skyline spectrum
Added 2025-04-26 08:48:57 +0000 UTCI got a sheet of diffraction grating filter and used it te make a spectral filter. This is all still part of the Light Bulbs video I'm working on, which is now about 25 minutes long 😱 I'm making good progress with it, only waiting for one more light bulb 😇
