The author of the text, Kevin Thompson, attended Twilio's SIGNAL conference where they set up a massive 40-foot video wall and handed out hackable wireless badges to attendees. The author found that they could send commands to the badge using a short code, which would affect their personal block on the video wall. After figuring out how to send text messages programmatically through the Messages app on their MacBook, the author used Ruby to create a script that could draw pixel art on the display by sending instructions as text messages. The script utilized the RMagick library for ImageMagick to manipulate images with Ruby and convert pixel data into a series of instructions that could be sent to the video wall application. To optimize the script, the author omitted transparent pixels, which significantly reduced the number of pixels needed to draw an image, making it possible to display test images on the video wall in a reasonable amount of time. The author successfully sent multiple images to the video wall, including a pixel art avatar of Phil Nash from Twilio, and documented their process and findings on Twitter and Gist.
