This is a fun little trick hidden within Twitterrific 5. It’s an Easter Egg that gives you pixel-style text.
Here is a Tweet from the developer’s official Twitter account:
Easter Egg: Tweet “OMG Pixels!” w/ Twitterrific v5 for iOS to unlock a special retro theme font, Pixel Lover. #8-bit 🙂
That’s pretty cool, especially if you are into that retro pixel look.
