Back in 2007, a bunch of US crazy starts up appeared, who were attempting to make mind-controlled games a reality.
The idea was to sell you a headset that would measure your brain waves, using them to control in-game action.
By 2008, they seem to have disappeared... or did they?
Because Icelandic developer MindGames has just launched 28 Spoons Later, a zombie spoon-bending game controlled by the player's mind, which uses a PLX XWave headset from NeuroSky (one of those crazy start ups).
The game's conceit is that the player has been kidnapped by a gentrified zombie, who despite wanting to eat the player's brains will only do so with the aid of a spoon.
The player has to focus in order to bend the zombie's spoons using only the power of their grey matter to avoid this fate.
"28 Spoons Later is a mind training game, which helps you to train in the important mental habit of focus while having fun," said Deepa Iyengar, CEO of MindGames.
"This game is a first step toward our development of clinically effective mind training games. Such games could be used by psychologists and psychiatrists in medical centres to train people who have problems with attention."
The game itself is available as a universal app on the App Store for $4.99 while the headset, currently on sale at $99.99 (regular price $149.99) can be purchased directly from the PLX devices website.
