From the developer's website: Inkstrumental™ is quite simply a global hit sensation! ‘Make and Share’ your mental music video masterpiece with your friends and the world via YouTube. ustwo™ teamed up with acclaimed artist Jon Burgerman to create what is possibly the craziest sound app ever for the iPhone. Original animations, bizarre sound effects and the unique Burgerman aesthetic make up this highly addictive app, allowing users to create, save and share their sonic creativity. The idea for Inkstrumental™ is pretty straightforward, with users selecting a range of various Burgerman characters, each with its own crazy and fun sound when tapped (some characters make the beats, others the synth). The user can then decide which eight characters they want to create their own unique Inkstrumental™ masterpiece with, and once created users can share their soundtracks via YouTube to all.
