Saw the fun company Mastor Technology at the Photo Plus today. I had been intrigued by their pistol stabilizer before for Hero 3 and Iphones, featured here:

It was nice to see it in person. Workes really well. Basically it's a self centered gyro that allow you to electronically pitch and pan your devices (Black magic, GH3, RX100, you name it). The hand held 360 degree unit for black magic was especially interesting. PRiced at 9000, not cheap, but it completely froze my camera in mid air no matter how much I tried to shake it. really cool stock. check it out
