Early in 2022, Adafruit Industries showed off one of the smallest devices playing DOOM, in the Adafruit QT Py (QT Py ESP32 Pico board), and we suspect it is a version of this device inside the Mars bar running DOOM in all its pixelated glory.<\/p>\n
The video showcased by Adafruit Industries is only 22 seconds long and starts with them opening a MilkyWay bar (per the image above) and then showcasing a small screen running DOOM inside the candy.<\/p>\n For size reference, the fingers of the person in the video shows this is the size of an average human finger, running DOOM quite well.<\/p>\n We don’t see any freezes as the game runs smoothly through the Mars bar. At the end of the video, a catchy line states, “Do not eat if it’s Turing complete”.<\/p>\n For the uninformed, this “Turing Completeness” is defined as: “A computational system that can compute every Turing-computable function is called Turing-complete (or Turing-powerful). Alternatively, such a system is one that can simulate a universal Turing machine.”<\/p>\n All modern programming languages are “Turing complete”. In all fairness, it is just a fun way to say don’t eat this little piece of hardware.<\/p>\n This seems to be a plastic Mars bar that DOOM is running on, and it is not made to be eaten; not that you can get this in a shop or while trick-or-treating this Halloween anyway…<\/p>\n Check out the short but sweet (yes, that was intended) video from Adafruit Industries below.<\/p>\n
