          Reddit DailyProgrammer Challenge #180 -- Tamagotchi Emulator
            By Aerospark12 (aka Luke)
 
    I may have gone a little bit overboard with this one, but I've got fond memories of tamagotchi from when
  I was but a wee laddie, I've always wanted to make something like this, and I really enjoy graphics and animation

    The design of this is partially inspirte by how I understand "low level" ICs to work, as an homage to the real tamagotchi

Update May 2017

Eric Bidelman has documented some of the common workflows possible with headless Chrome over in https://developers.google.com/web/updates/2017/04/headless-chrome.

Update

If you're looking at this in 2016 and beyond, I strongly recommend investigating real headless Chrome: https://chromium.googlesource.com/chromium/src/+/lkgr/headless/README.md

Windows and Mac users might find using Justin Ribeiro's Docker setup useful here while full support for these platforms is being worked out.
