I saw this at a NAMM recently and it looked interesting but was vaporware at the time. Also, it required wearing an unwieldy contraption on your foot. Since then the folks at Chroma Coda have made some changes to the Poly Expressive concept that makes it more attractive (getting rid of the footwear, for starters). They have also launched a Kickstarter campaign. What do we think?
