A "kind of" multiplayer game idea.

Whether it's practical or not, the idea itself is very creative. I certainly never would've thought of it.

I wonder if you could use a collaborative Google spreadsheet to do this.

Well, it lags a bit. If it were a chess game or a turn based game that wouldn't be a problem.

Definitely this not work well with real time games/simulations.

Sorry for the black bars on the videos, i still have a CRT as main screen and i'm filming with my Nokia.

Here is the box moving simulation sending X Y and angle values through a WiFi network between two pc's.
