Here's a description of every icon, since I wasn't able to include them in the demo.
Gameboy Icon - A blast from the past! This icon is inspired by the Nintendo Gameboy's color palette, evoking a sense of nostalgia. It features a pixelated environment set against a sky backdrop with the pixelated Telegram logo.
Retrowave Icon - Back to the 80s. This icon embodies the iconic design style of the 1980s known as Retrowave, characterized by its vibrant and retro aesthetics.
Space/Universe Icon - Into the Universe. This icon showcases the Telegram paper plane venturing into the depths of endless galaxies, surrounded by glistening stars and vivid space auroras, creating a sense of cosmic adventure.
Sky Icon - The simplest of them all. This icon is the most basic in the pack, serving as a remastered version of the default Telegram icon. It features the iconic paper plane flying through the sky, within dense clouds, as you send your message across the world.
