1. /dev/null listener

Post some data to /dev/null and read the response. Really interesting though quite predictable.

2. Scrambler

Scrambler: scrambles all letters in every word except the first and the last one. Yes, I did warn you: they're really silly!

3. Latinic to Cyrillic

Lat-Cyr encoder: converts latin text to a mess of cyrillic characters and numbers which are supposed to look similar.
