Blown away by the surface patterns my Bambu printer can make

I've noticed that the quality of Bambu printers, combined with modern aesthetic filaments and shiny build plates, produces sick effects. While I found some sample test models on Maker World, I couldn't find anything which simultaneously included both top and bottom surface patterns, so I created a new test model here: https://makerworld.com/models/753044

Bottom surface patterns in particular really bring out striking qualities of some filaments. I've printed many models to take advantage of this effect. Signs, coasters, and anything else with a visible flat side can really benefit.

Build plates used in the video: The "light beam" and "starry" holographic build plates for my P1S. While such plates are often described as "holographic," the term "prismatic" is more accurate. These plates are sold on AliExpress, Amazon (double the price but quicker shipping), and Bambu also sells sticker sheets (but not pre-assembled plates). I've enjoyed all of the patterns in which these plates are offered except for the alphabetic/numeric ones, since those symbols show up backwards. Note that some people have problems getting things to stick on these plates, but I haven't had any issues when setting the first layer temperature to 68 and all other layers to 60.

Filaments used to produce the models in the video: - Comgrow tri-color silk PLA - red/blue/green - Bambu Galaxy PLA - purple

I love how both of these filaments turn out on the prismatic plates, but it's worth calling out the hypnotizing iridescent effect of the Bambu Galaxy filament. You can usually only see this effect somewhat, but a prismatic plate + Hilbert curve will turn it up to 11. Bambu describes these filaments as containing glass microspheres, but the difference between that and regular glitter wasn't obvious to me until I printed on a shiny plate. These microspheres are totally different and don't look cheap like glitter, IMO. I have other brand galaxy filaments and they're not the same thing at all. The closest I've come to Bambu Galaxy is Ambrosia Color Shifting (and to a lesser extent Polymaker Starlight), and I'm eager to learn if there are other filaments which sparkle in this unique way.

Side question: Does anyone know of any highly glossy build plates similar to the "holographic" ones, but without any pattern? There are times I want high gloss without having a prismatic effect, but all the regular smooth plates I've seen are matte.
