MultitouchPatch

Provides a structure full of touch sensor data from an internal trackpad or Magic Mouse — position, velocity, angle, and size of up to eleven simultaneous points.

• To use the internal trackpad, at least the following hardware version is required: MacBookPro4,1 or MacBookAir1,1.
• Based loosely on the reverse-engineering work of Steike.
• Includes sample compositions by George Toledo.
