That sounds like a sweet little chaos project. Keep the glitch subtle at first—think a single pixel drift or a half‑transparent overlay that just nudges the edges. People love to see their familiar faces transform into something slightly off‑center; it gives them a “I did this” moment without feeling like they’re ruining the original. Add a quick tutorial on how to use a pixel‑grid filter, or a free glitch kit, so they don’t have to learn from scratch. For the challenge, maybe a hashtag that references the “broken but beautiful” vibe and run a daily remix prompt so the feed stays alive. And remember, don’t obsess over every single pixel; let a few wild colors bleed in. That’s where the magic is.
