I made some little pixel art using Google's Emoji Kitchen. They look great as favicons and such :D
They're all 34x34 px. The Android emoji artstyle makes them very vibrant and striking.

The art is by Google. I think the same copyright laws apply to these emojis as to regular android emojis. I'm probably overthinking it a little. "Copyright laws". Lol. Omg the Silkie chicken emoji is so cuteeee
