These days George Takei is almost as known for his Facebook page as his former role as Sulu in Star Trek, and he frequently shares images to his 2.8 million-plus followers. A new visualization from Stamen tracks how these photos spread across the internet, starting with Takei's original post. Branches in two colors represent shares from each gender and fade after time, with new "explosions" signaling short activity bursts. What you see above is an image of Marvin the Martian that Takei shared in August to parody the NASA Curiosity rover's Mars landing, but we recommend watching the video below for the full effect.
