There have been plenty of implementations of Pong over the years, given how long this retro video game has been around and how popular this simple content still is.
Playing Flash versions in a browser window is old hat, so how about using the browser windows themselves as the ball and bats?
That’s what the developers at stewdio.org have done.
Browser Pong has been written to take advantage of the latest HTML 5 specification, which is why it doesn’t work in standards-mashers like Internet Explorer.
Graphically advanced it’s not, though if you fancy cheating it’s pretty easy — just expand one of the “bat” browser windows fully vertically. Easy.
