If you're an old Amiga gamer, the term 'guru meditation' will bring back memories good and bad. Good, because it reminds you of a wonderful age of gaming focused on the Commodore Amiga, and bad because seeing a guru meditation flash up on the screen meant your awesome Amiga had just crashed.
New iPhone game Guru Meditation revives an Amiga-made peripheral released in 1982 for the Atari 2600 called the Joyboard, which is essentially a more primitive version of the WiiFit. The game involves sitting cross legged on the Joyboard while remaining as motionless as possible. By keeping still, the yogi on screen begins to float - move, and his concentration is broken and he floats back to Earth.
The iPhone version works in the same way; requiring you to sit in motionless meditation to allow the yogi to rise to video game enlightenment.
