I've proposed a new logo for Antox that is open source app.
Antox
Antox is an Android 4+ client for Tox created by Mark Winter. It aims to bring the full multimedia support Tox offers to your device, although it's still currently in heavy development. Antox is currently available for alpha testing on Google Play and F-Droid.
