Duncan Jones' hand-drawn SOURCE CODE timeline

Here is a cool hand-drawn timeline of Source Code from director Duncan Jones. I loved how this movie existed in alternate realities, much like Moon. The image above was shared via Twitter. While it may be a bit tough to follow, it at least helps explain things a bit. It is pretty cool that Jones created the timeline for his fans. He tweeted - "been rummaging paperwork from SC & found doodle I did for buddy during production." What are your thoughts?
