Here is a cool system that might encourage me to finally catch up with my unread e-mails. Designed using Arduino and Python, you get an M&M piece for each email you receive. When you read an e-mail, you will get your rewards. A pretty fun idea by Kathryn McElroy. You can read all about it on her Tumblr. If this doesn’t encourage you to learn Arduino and languages like Python, I don’t know what will.
