John dropped this update on us over the holiday, the pong watch is almost done!, He writes -

“I succeeded in compressing all the electronics for this watch in to a 10mm-thick case. The 96×64 OLED display runs continuously – unlike older LED watches, there is no need to press a button to see the time. Battery life is 25 hours, so recharging is done every night.” [via] – Link.
