We are from Kitronyx, Inc. We developed a capacitive multi-touch trackpad for Arduino and microcontrollers. It uses Microchip's MTCH6301 and bundled with several example Arduino firmware.
Although multi-touch is popular now, this funny technology is not widely used in Arduino community. We hope you to enjoy this multitouch during your project.
Here are links of demo videos:
