I have made a couple of Twitter bots, you can check the details here.
A bot that creates an image with a slightly different color everyday, based on the day of the year. Creating a beautiful rainbow one day at a time.
You can follow the bot. Source code is public on Github.
This bot tweets in spanish. It calculates whether is today a payday or not and tweets it daily.
The source code for this bot is public on Github. You can follow it here.
