Here's a human-interface challenge for you: what's quicker, typing in a three-digit channel number on a traditional 0-9 keypad, or locating a physical button for that channel in a 20-inch long rainbow gradient of 102 identically-sized buttons? Art Lebedev is apparently hoping to solve that age-old dilemma with the Pultius remote, a concept created in response to a challenge to "design a remote control with as many buttons as there are channels on TV." Since it's just a concept, there's no word on price or availability, but really, we've learned not to expect that sort of thing from Art Lebedev at this point.
