Artist Ben Rubin has found a creative way to pass the time on his daily commute to and from work— by doodling on his iPad.

If you’ve ever been on the subway in New York City you know there’s never a shortage of bizarre and interesting things happening. It’s the perfect setting for Rubin’s cartoon characters which he humorously integrates into his immediate surroundings.

You can follow the ongoing series, entitled Subway Doodle, on Instagram and Facebook where he is quickly amassing a loyal following.
