Crazy Eyes by Killerfeeshy is a fun app that lets you choose a pair of eyes from a list, then lets you control the winking of each eye (separately or together).

Changes:

* Added the ability to use your own sets of eyes in a menu inside of “Select eyes” called “Eyes options” where you can then choose either “default eyes” or “custom eyes” (Includes instructions)
