Screen Pixel to leds (HUD for game)

[remisarrailh]

A cool thing to do with leds, is to scan pixel on a screen in a game to make a custom HUD.
Here is an example that grabs the health of a player and display it on leds.
(that probably doesn't works since there was a lot of changes in the GUI for heroes of the storm that doesn't use websocket)

We could make a client, that would scan specific pixels on the screen, and use this information to make a led change color depending on what happens in game.
We can't do this with fullscreen game, but windowed fullscreen game works.
