Show HN: Antimemetic message that escapes screen capture

3 points by Leftium 23 days ago · 0 comments · 1 min read

The message is clearly visible, but it cannot be screen captured. (Or just pause the effect with click/tap.)

I think this TV static effect is more realistic than others on the web:

- Wide CRT "pixel" aspect ratio

- Larger "grains" (to match low CRT resolution)

- CRT "scan lines" (Toggle with 'C' key)

When I attempted this effect many years ago, it didn't seem possible without GPU shaders. With advances in hardware/JS performance, the CPU can easily blast a higher resolution (2560x1440) at 1000 FPS. (ENTER key to go into fullscreen mode)

Customize the message with url param: https://fx.leftium.com/static?text=HN

(To see all options: 'U' key copies URL to clipboard and also outputs to dev console.)
