I think I want one of these…
“HP’s DJammer is a prototype handheld gadget DJs can use to mimic the sound of scratching vinyl simply by moving the device around. So, if the operator makes a scratching motion in the air, arrays of internal motion sensors translate movement into music, and the DJammer “scratches” the music as though the DJ were manipulating a record.”
Unfortunately: “…the DJammer has yet to be made into a product…”
Maybe one day… 🙂
