Tetris In 140 Bytes
mikejuk writes "Is it possible to write a JavaScript program in no more than a tweet's length? A website called 140byt.es says it is and has an implementation of Tetris to prove it. Ok, it only has two types of block — hence its title "Binary Tetris" — and there's no rotate, but it works. The blocks fall down the screen and you steer them into place. You can try it out by playing the demo. Of course the real fun is in figuring out how it works and there is lots of help on the site — so if you're bored how about the 140 character challenge?"
It reminds me of the old days when code was efficient and had to fit onto small discs and into limited RAM and/or ROM. The original Mac ROMs were 128k, and all the apps had to run in 128k of RAM. It was amazing what could be done when it just had to fit.
