iKoto strums the iPhone's strings
Traditional Japanese harp-plication now on the App Store
Admittedly, it's not really a game, but we were forced to raise a happy smile when we saw this one, so felt like it was worth a mention.
GClue has released a koto (traditional Japanese harp) simulator for the iPhone, called iKoto. Ideal for budding cyber-Samurai looking to get in the right frame of mind before battle, or possibly for techno-buskers aiming for a slightly different market on the London underground, iKoto has literally several uses. It'll even record your performances and play them back when you need to feel a bit more zen.
Check it out below, and don't be shy if you feel that a quick run up and down those wonderfully traditional strings is worth 59p. We'd be inclined to agree.
