Hello, Habr! Say , laziness - the engine of progress . But no one said that this very engine would be fast . My story is about how I made a visualization of Alice's voice assistant with a hologram effect from scrap materials.

It's a bad idea to use a TFT monitor
I also found an unusual application for such a device: instead of Alice, display the time or timer before some event with the backlight on.
While recording a video of Alice's rendering, I used a test animation of movement. The effect is as if Alice's model holds the light above it and goes to the user. I thought it was funny and decided to leave it that way.
