This Business Card Runs Linux And You Could Build One Too
According to Hilliard, his idea for the business card came to him when he thought, “These processors are nearly cheap enough to give away.” He noted that he had seen electronic business cards before, but their functions tended to be rather limited.

This business card is definitely next-level and could be a fun way to show off your skills. Hilliard has kindly provided a detailed how-to and his source codes; you can find his full description and sources here.
