Decades before there were LCD displays, Nixie tubes showed off digits in glowing vacuum glass containers. Their retro appeal and geek cred have led them to adorn the wrist of Apple co-founder Steve Wozniak. And while they’re a tad impractical for such a small timepiece, they have no problem working on the aluminum brick that serves as the base of Blub. Due to ship in backers in May, the clock is more art than functional timepiece, as one would certainly surmise from its $369 AUD price tag. It features a night-time shutoff and an alarm, although you probably shouldn’t try slamming it as you would a snooze button.
