ELAN's Ole is a touchpad controller for home A/V systems. It features a touch-screen layered over a skinnabled 'slide-in-film'. ELAN says that "the photographic-quality films slide easily into the touchpad, transforming each in-wall controller into a work of functional art".

It also features a 1", 65K color OLED display.
