This section uses Intel One Mono with sourceRandomCharacter = "░▒▓█".
Move the pointer over each line to replay the block character effect.
This section uses Google Sans Code with sourceRandomCharacter = "░▒▓█".
Move the pointer over each line to compare the rendering.
This section uses vertical block heights: "▁▂▃▄▅▆▇█".
These characters create a bottom-to-top gradient-like texture.
This section uses Braille patterns as a density ramp: "⠁⠃⠇⡇⣇⣧⣿".
Braille can produce fine texture, but rendering depends more on the font.
