HBO static logo #static

u/Agnes

I tried for like two hours to make the logo do the "noise inside -> white on black" transition and there's just no way. You can almost do it with x.clip(new Path2D()) and an SVG path for the letters but I couldn't get it below 250-300 chars.

Wow, that's amazing!

Nice! recreating media is always tricky when there's typography involved.
