The iAno is - you guessed it - a virtual piano for the iPhone.

This is available now as a free download for jailbroken iPhones. Let’s hope that when Apple officially opens up the iPhone to developers that they let everybody get at this sort of delightful weirdness.

Features

• A complete four octave keyboard.
• Multi-touch. Up to 5 keys can be pressed at once allowing complex chords.
• Sounds like a real piano with realistic piano multi-samples.
• Animated piano keys react to your touch.
• Play along to all your MP3s.
• On-screen keyboard navigation allows you to easily move up and down by octaves or “part octaves” (ie. left-most key is a C or an F).
