The exuberant early-internet aesthetic: chrome metallic buttons, bubbly fonts, silver backgrounds, and the hyper-optimistic visual language of year 2000.
Chrome and silver metallic gradients on buttons and bars
Bubbly rounded everything with iridescent sheen
Bright saturated secondary colors (cyan, magenta)
Drop shadows everywhere, often with color tinting
Pixel or bitmap textures combined with metallic gloss
Y2K Design works best for these industries
