Twist, turn and twist it again. That pretty much sums up this neat little invention. The people at DsLabs came up with the idea of a physical knob having the same feel of your finger when applied to the screen. The point behind the invention is to make it easier to rotate objects on the screen.

Since it’s so touchscreen friendly, not only does it work for the iPhone but it also works for the iPod touch and the iPad. The stylus knob was created with the same technology that other touchscreen-friendly styluses have, except this stylus only rotates.
