Kaomojis are like emojis but in the form of text strings like:
this happy guy ＼（＠￣∇￣＠）／
or this dude flipping over a table (╯°□°）╯︵ ┻━┻
Kaomoji Cat is a webapp that helps you find the perfect kaomoji to express how you're feeling.
While there are way more kaomojis than emojis, kaomojis can be more flexible and expressive. I played off that quirky expressiveness with the character of the Kaomoji cat, fish and red string. The cat and his app hopefully comes across as cute, precocious and maybe a little bit creepy.
