May I present to you the latest innovation in whiskey perfection: the ice sphere. Apparently rounded ice cubes, having less surface area than regular boring old six-sided ice (or D4s or D20s or whatever other shapes they make ice trays in these days), melt slower, thus ensuring more nursing time for you and your drinkable accessory.
This means you can finish that crucial point about the electoral process or how it was really you who broke up with that jackass or which Miles Davis album you prefer without interruption, while your half-chugged tumbler of ripple doesn't completely melt away into Kool-Aid. Also, it looks real cool in the glass, which is certainly a consideration, I ain't gonna lie to you.
Taisin (Warning: Japanese!) makes special ice molds that create perfect seamless round ice balls (they claim at the rate of 30-40 per hour, which means every two minutes or so, which seems a bit fast to make an ice cube, but they do sound rather like engineers, so I wouldn't be surprised if this was accurate and my skepticism was completely unwarranted).
